audio only ota channel bug

In Atlanta we have some ota digital audio only channels that rebroadcast local radio stations. They will not tune on the premiere but tune fine on the series 3. This problem is specific to over the air channels that contain no video and only audio. the dvr statistics show a solid signal strength and good SNR. Has a channel lock and signal lock, with no errors showing up, but the premiere just says problem with the signal on this antenna channel, it tunes the same sub-channels that have video and audio just fine.

Well, my Premiere XL finally died. After slow performance and random reboots over the past few weeks, it went TU yesterday.

It is not a question of IF but WHEN yours will fail.....................

Make sure you get that extended warranty.

Echo:
Sometimes, when I fast forward through a program and come to a stop, the audio has an extremely echo sound. When I hit the 8-second back button the audio returns to normal. Weird. )

I too have noticed this.

I have this issue too. I always assumed it was a problem with my receiver, but considering others are having it, I guess it might be the Tivo. I'm using an old (~90s) Sony receiver with an optical audio connection.

After only 2 years or so? Scary.

Every device will fail at some point. hard Drives fail. Some sooner than others. But personally in over ten years with TiVos I've never had a hard drive fail. And in using hard drives for twenty years, around 200, I've also never had one fail after being put into service. Well at least not yet. But I've beat the odds so far.

Even my DirecTV TiVos that I upgraded to larger drives ten years ago are still working. I gave them to some friends years ago and they still use them daily.

And hopefully I didn't just jinx myself, since my launch Premiere XL is over 25 months old now.

OK, that is not likely to have started as a problem in 20.2, but it is worthy of adding as an "unresolved" issue. Unfortunately, I have a feeling few areas have the ability to test/confirm it; I know in my area, there are no such audio-only stations.

Please note that a new changelog thread has been created for those changes specific to 20.2.1.1 and can be found at the following URL: http://www.tivocommunity.com/tivo-vb....php?p=9088054

Not that this is scientific or anything, but previously I stopped editing the prior changelog when new software was released. If we discover other issues that might have been introduced in 20.2 (instead of 20.2.1.1), they can still be added to the new thread. This way, people only have to look at one thread.

SW Version 20.2.1.M4-01-2-746 was a leaked beta trial version prior to the current SW Version.

The current SW Version should be 20.2.1.1-01-2-7xx

Question cable channel scan

Hi All,
Did the 20.2 update remove the QAM channel scan? Is there a way to force a cable scan or revert back to the earlier firmware (14.9)? All it does now is ask for a zip code. I've tried to search for more information, but I haven't come across anything (or am searching for the wrong terms).

Backstory: I've been using the Tivo Premiere as an HD tuner for my projector without a subscription for about 9 months now. I was able to pick up the local broadcast channels in clear QAM. In the past, when selecting Cable in the guided setup, it would scan for all the available cable channels (including clear QAM), not just ask for a zip code. Our cable was cut about a month ago, so I re-ran the guided setup to use an antenna, but it fouled everything up.

Thanks for any comments/suggestions.

Are you talking about 20.2 update or 20.2.1 update? You posted to the old thread.

I can't answer the QAM question, but I am very curious to know the conclusion (once I know which version you are really using)...

I have a TP with 20.2.1 without TiVo service and I have done the QAM scan without problems.

Either I am misremembering or you are. Every TiVo I have ever owned over the last 10+ years asked for a zip code at the beginning of guided setup.

How did you get the update if the TiVo is unsubscribed?

What do you mean by "it fouled everything up"?

I need to doublecheck my version - I do realize I posted in an old thread, but I've been having the issue since before this latest update. I don't recall if it prompted for a zip in the past, I just know now that it doesn't QAM scan anymore, but rather picks a lineup and sets the channels that way.

For instance, when I put in my zip, 77346, it brings up 2 Comcast lineups - basic and extended.

I guess I also need to doublecheck my cable line to that room is still working by bringing in another tv. I'll try and post back with my version tonight. Thanks for the responses.

By fouled everything up, I meant I lost all my QAM channels and the only way I get tv is by using the antenna. Prior to this, I only used cable/QAM channels, but when I did cable/antenna, I lost the original channels.

You have me totally confused. Is the TiVo subscribed or not? How do you expect to complete guided setup on an unsubscribed TiVo? Has your cable been cut or not? Have you tried doing a manual channel scan (Settings->Channels->Channel Scan)?

BTW, IMHO none of the changelog threads is the appropriate place for this exchange.

Tivo is not subscribed and has never been.
Completed the guided setup in the past without any issues.
Cable was cut about a month ago and was repaired (the line running to my house). While it was out I repeated the guided setup and lost the QAM channels I previously had while trying to add OTA tv channels. I have since re-run the guided setup after my cable was restored, but didn't have the option to do a cable channel scan.
I've looked for the channel scan previously, but I do not think it's an option.

Mods feel free to delete my posts, I was more curious if anyone else was having the issue. I appreciate the responses - sorry if I upset you.

An unsubscribed Tivo has to complete guided setup, otherwise how would the Tivo know what your channel line-up is?

A Premiere will work as a dumb cable box without a subscription.

Why does an unsubscribed TiVo need to know what the channel line-up is? You can't get guide data unless you are subscribed. You are supposed to register your TiVo before you start guided setup. When it connects to the TiVo service, if it is not subscribed, I thought it would terminate the connection. I think there may have been a 30 day period when first set up. He's way past that.

With no guide data. The channel scans are what finds the clear QAM channels and OTA channels. Has nothing to do with channel lineups.

I would like to ask pnut what the System Information screen has for "Tivo Service Account Status"?

I will check when I get home tonight.

Yes, I am able to complete the guided setup without having an account or subscription. I'm not interested in the guide or other features, I just want to be able to use the Tivo as a tuner to tune the QAM channels I have, but it's not prompting to do a channel scan on cable (only antenna).

Thanks again

As far as the channel scans are concerned, that is the correct behavior. You should be able to force a cable channel scan through the method I outlined earlier. I did one yesterday on my new Premiere. Still negotiating with Comcast about what they want to charge me.

Well I got home and found a message on Tivo saying that I have been updated with the Spring update. And wouldn't you know it, I was able to kick off a channel scan. Strange stuff - will post back with results. Thanks again for the responses.

Software Version is 20.2.1.1-01-2-746
Tivo Service Account Status is 7: Never Set Up

Channel scan was successful!

A brand new Tivo out of the box will give you a 7 day free trial of the TiVo Service. It has to complete Guided Setup to accomplish this goal.
In general, guide data and channel line-up are separate entities.
Any Tivo will have to go through Guided Setup (basically an enhanced channel scan) just to get the channel line-up for its location. It's the TiVo Service that maps the guide data specific to the channel line-up of the area.
It is not like the old days when channel X appeared on frequency Y no matter where you were. An unsubscribed Tivo does not download guide data, but it does rely on correctly mapping the channel line-up for a given area.
If your cable company puts HBO on channel 123, the Tivo needs to know that regardless of the subscription status. That way, when you enter '123' on the remote, you will be tuned to HBO. That is essentially what Guided Setup does.

Tivos have never been set up to deal with QAM channels without a cable card. They are able to tune them, only there's no guide data associated with them.
I suspect TiVo has changed the software to ignore recognizing QAM channels without a cable card on unsubscribed Premieres. This would fall in line with the fact that they disabled the live TV buffers for unsubscribed Premieres.

Actually that's what the cable card does. It decodes the channel lineup broadcast out by the cable company in the OOB data. That's why you can still tune channels via number, even if those channels have no guide data. So technically as long as a cable card is inserted, guided setup is not required for an unsubscribed TiVo. In reality it is needed since the box won't display the menus until guided setup is complete.

My using HBO as an example might have been in error since that is a premium channel and a cable card would be needed to correctly tune that channel.
But what about all the basic channels that can be tuned with a simple cable ready TV without a cable card? That is the issue here. The Premiere has (supposedly) lost the ability to tune QAM channels on unsubscribed boxes.
To me, this suggests TiVo is catering to the cable companies more than ever these days.

To me, this suggests TiVo is catering to the cable companies more than ever these days.
The ability to tune QAM any channel by number is entirely dependent on whether a cableCARD is inserted or not. The cable company sends the QAM channel map embedded in the signal. The Premiere can only decode that if it has activated cards inserted. No cards, no channel map, no channels. The only reason to scan for QAM channels is if there's either no card inserted or the cable company screwed up the channel mapping. I suppose there could be a software issue preventing mapped channel that aren't in the guide from displaying like they used to, but that has nothing to do with scanning. See http://en.wikipedia.org/wiki/Digital_cable#Channels

The guide data that the Premiere downloads simply maps program info to a specific channel number. That channel number may be incorrect or not even exist. Similarly channels can exist and be tunable without TiVo provided guide data. That's why there's a lineup issue form on TiVo's web site for fixing problems where the cable company and TiVo's (Tribune's technically) mapping don't match up.

I'll mention some cable companies encrypt (which isn't the same as copy protect) most cable channels (Comcast is starting to encrypt all channels, even basic, across their entire footprint). Encrypted channels cannot be tuned without a card.

In general, guide data and channel line-up are separate entities.
Any Tivo will have to go through Guided Setup (basically an enhanced channel scan) just to get the channel line-up for its location.
The channel lineup is downloaded from TiVo. It has nothing to do with a channel scan, enhanced or otherwise.

It is not like the old days when channel X appeared on frequency Y no matter where you were. An unsubscribed Tivo does not download guide data, but it does rely on correctly mapping the channel line-up for a given area.
If your cable company puts HBO on channel 123, the Tivo needs to know that regardless of the subscription status. That way, when you enter '123' on the remote, you will be tuned to HBO. That is essentially what Guided Setup does.
No, it does not. The only reason a TiVo needs a channel lineup is to associate the guide data with the proper channel. There is flat out no reason to give a channel lineup to an unsubscribed TiVo. TiVos were never intended to be used as dumb tuners.

I suspect TiVo has changed the software to ignore recognizing QAM channels without a cable card on unsubscribed Premieres. This would fall in line with the fact that they disabled the live TV buffers for unsubscribed Premieres.
A cable channel scan may be done automatically during guided setup if you say that you don't intend to install a CableCARD, I've never set up a digital tuner TiVo like that. You can explicitly do one, but only if you have no CableCARD installed. For the most part, what you get when you perform one is channels that are in the same format as the Broadcast channels. For instance, I currently have both 5-1 WAGADT Fox 5 News at 10:00 (the OTA channel) and 5-1 WAGA HD To be announced (the clear QAM channel) visible in the guide. The channel number and call sign are imbedded in the digital stream and are set during the channel scan. I also have 4 WAGA Fox 5 News at 10:00 and 804 WAGADT Fox 5 News at 10:00. Those are the is SD and HD cable channels respectively that 5-1 gets mapped to. That's from the TiVo channel list that got downloaded during guided setup.

Why do you think the TiVo needs your zip code and cable system? So it can select the correct channel lineup. It also asks you to verify what is on specific channels because sometimes there are minor variations even within a local cable system.

You've obviously never selected the wrong lineup during guided setup or you'd know that a channel scan has nothing to do with it. I have.

As far as pnut's particular situation is concerned, it makes no sense. How can the status be "Never Set Up" when he just finished setting it up? Especially since he's WAY past the 7 day "free" period.

"Never Set Up" is for the TiVo Service account status, which means the DVR has never been activated with TiVo.
You can set up a Tivo without setting up an account to get service.
What happens behind the scenes during guided setup, I don't know. I just know that to the end user, it makes no difference whether the DVR is subscribed or not.
I suspect that an unsubscribed Tivo does everything that a subscribed Tivo does during Guided Setup. All the features are there, they're just "locked out" by the software.
That way if the Tivo is ever subscribed, it will instantly be ready to use.

In addition, connecting to the Internet for Guided Setup could allow TiVo to install the latest and most restrictive software on the box.
