    Went to watch Mythbusters tonight on the TiVo in my bedroom, and of course it didn't record it. Tried tuning to 1618 (Discovery HD) and just get the "Channel Not Available" message for a split second and a black screen. Other HD channels are the same.

    I went to look at the Tuning Adapter diagnostics screen to look at the Tuner, RDC and FDC numbers, but was told that the diagnostics are not available. I rebooted the TA, but nothing changed. I'm rebooting the TiVo.

    I have little faith that calling TWC will result in this issue being resolved. If someone does, through some miracle, actually get a resolution to this I'd love to hear it. Every day that goes by where my recordings are missing and/or I have to reboot my TiVo to watch TV is one day closer to my calling DIRECTV.

    The fact that rebooting the TiVo will (temporarily) fix this issue really makes me wonder if TiVo is somewhat culpable.

    Okay, now that my TiVo has rebooted, I can get into the TA Diagnostics. Here are the values for Tuner, FDC and RDC:

    Tuner: -6 dBmV
    FDC: -2 dBmV
    RDC: 44 dbMv

    As you should have seen in the posts I linked, these are acceptable values AFAIK. Unfortunately it looks like you may not be able to read these values when things are "bad". However they are important, since they are OK during normal times. If they were out of range that would be suspicious.

    What was the TA light doing when you discovered the latest problem?

    When you rebooted the TA, did you also disconnect then re-connect the USB to TiVo? This might save you having to reboot the TiVo. After you reboot the TA, wait until the TA light is either solid or blinking the 6-blink-pause sequence before reconnecting the USB.

    Whenever you're done trying things I think it would be worth a call to TiVo support. Hopefully they will get you connected to TWC's National Cable Card Support people, who are your best shot at actually knowing what is going on. This is the way it worked for me when my TA lost provisioning.

    Good to know those are "normal" values, thanks. The next time this happens on either of my boxes I'll try going into the TA diagnostics screen again to see if I'm able to access it. The fact that I wasn't able to last night certainly suggest that TiVo has lost communication with the TA for some reason.

    It was solid green.

    The first thing I tried was unplugging the USB and plugging it back in. This did nothing. I then rebooted the TA, but did not try disconnecting and reconnecting the USB cable after it was finished booting. Next time I will try that and see if it saves me having to reboot the TiVo.

    I believe I've become quite cynical towards support for technical issues of this nature, but I am willing to give TiVo support at least one call to see what they can do. :)

    Thanks,

    ..Al

    This problem is infuriating. I have the STA1520 on two Tivo's (one an S3 and one an HD). They both exhibit the same problem -- random locking of the STA1520. When the device locks, I can't tune any HD channels, and they can't be powered off with the button on the front. The way I resolve the problem is to pull the plug on the STA1520, and then reboot the Tivo. Perhaps rebooting the Tivo alone fixes this problem, but I haven't tried that yet. I do know that only power cycling the STA1520 doesn't fix the problem, but it does fix the locking of the tuning adapter such that the power button works.

    I love the Tivo interface, but I'm seriously considering switching to another provider such as DirecTV. I shouldn't have to micromanage my DVR. I never had to in the past.

    Well, you are now the fourth person from Austin chiming in with this issue, so I think that's enough data to demonstrate that there is something awry going on.

    I agree--I'm a very technical person, but as you said, having to micromanage my DVR is the last thing I really want to have to worry about. When I sit down at the end of a long day to watch some television (which I don't do a heck of a lot of), I want whatever programs I recorded to be ready to go. Instead of relaxing recently I've just been getting frustrated.

    You might avoid having to reboot the TiVo by unplugging the USB cable before you reboot the TA then wait for a solid green light or the 6-blink-pause sequence before connecting the USB.

    Also be sure you're TA is getting some ventilation.

    Have to agree there's a pattern in Austin.

    I am another TWC user in Austin with two HD Tivos with TAs who lost all ability to watch or record any channel this week. Rebooting the systems solved the problem, but I called in anyway to complain. They gave me a refund on my HD Tier bill for 90 days and transferred me to support who promptly told me this was a common problem with TAs. The inference made was that I should just accept it and shut up.

    I hate this crap.

    In my case, I discovered there was a problem after being away for a couple of days and all my scheduled recordings were either blank or not present. it kinda defeats the purpose of having a DVR if you have to watch live TV several times a day to ensure they are working properly, especially if you are away from home quite a bit.

    You've got to realize TiVo digital subscribers are not part of TWC's business plan! They would be happy if we just vanished, or even better, switched to their DVR's.

    Won't it be satisfying whenever you get away from TWC ?

    YES!

    I have a Home Theater PC wit four HD Tuner cards in it, and it works perfectly day after day, year after year.

    I don't blame my Tivo for these problems, but I am growing to hate TWC more every day.

    Seriously? If I call TWC and I get this same response, my next phone call will be to DIRECTV and my next call to TWC will be to cancel my television service. I sure hope new DIRECTV TiVo boxes are still coming out next year.

    All of my experience with DIRECTV is that their HD signals look terrible - and I have many friends and family members with DIRECTV. I don't need low quality TV, I'd rather read a book.

    I haven't looked at DIRECTV in a long time. I will need to do so before I make any decision to switch. PQ isn't that great with Time Warner either. U-Verse is another option for me, but not sure I want to go down that road. Had that early in the year before I moved to my current residence and I wasn't happy with their HD picture quality.

    Having read about problems getting TAs in the Hudson Valley, I called TWC last week and asked if they had any TAs in the Port Ewen office that I could pick up on the weekend. They called the Port Ewen office and they gladly held one for me.

    So, try calling in and asking nicely before you make the trip :)

    Got home a few minutes ago to find that the TiVo HD in my living room was completely locked up. Black screen, not responding to input, and not even displaying the yellow LED when pressing a key on the remote. The Tuning Adapter was blinking, and I power cycled it.

    I rebooted the TiVo and after it finished booting I hit the "Live TV" buton. The menu went away (but the background video continued playing) but the TiVo locked up again. :rolleyes: After booting the TiVo a second time it seems to have worked (it's acquiring guide data now).

    Patience quickly dwindling. Haven't even checked the TiVo upstairs yet.

    Finally went upstairs to look at the TiVo in my bedroom, and it also was completely locked up. Both recording LEDs were active, but the TiVo was not outputting a video signal and not responding to the remote (no yellow LED when pressing buttons on the remote). The TA light was solid green. Rebooting now.

    This is getting quite ridiculous. I am sad. :(

    Add me to the list of people having trouble with TWC in Austin, TX (well, Cedar Park)

    TiVo HD + Cisco STA1520 tuning adapter

    Symptoms:
    - Loss of SDV channels
    - TA light is solid green
    - TA does not respond to power button
    - Tivo is unable to access TA diagnostics screen

    Tivo support has some sort of tech bulletin regarding "corrupted packets" locking up the Cisco tuning adapters but is unable to give me any info related to firmware revisions or possible solutions.

    I have a tech coming back today to swap out the TA but it sounds like that isn't going to do much. I'll do my best to get this escalated ASAP.

    The above symptoms are 100% TA related, but I'm also dealing with a hot signal issue (according to Tivo support). The Tivo is always pegged at 100% signal strength with a SNR of 38-40 dB. Tivo support suggested that I should target 80-85% and 32-35 dB. The TWC tech said that there was no such thing as too much signal and the line test looked good. I've tried attenuators but they drop the high frequency channels (700 MHZ+) below 50% strength and 29 dB long before bringing the low frequency channels to the suggested levels. Not sure if it is related, but it probably isn't helping the situation at all.

    I'm in Round Rock, for what it's worth. Thanks for your additional information. I hope there is ultimately a solution to this problem, and something relatively soon.

    TiVo support documents say 80-99 is the recommended range and as low as 65 is OK for the HD. I don't believe the 65. I think you need 80 or above.

    TiVo is right that you can have too much signal for an HD tuner -- TWC is wrong.

    I have variations across the channels like you, so when I get the lowest signals around 80 about a third of my signals are 100 (or above -- you don't know from the reading). I know they are only slightly above 100 because of what they were before I removed an attenuator. I seem to get by with them slightly above 100, I'm guessing 105 or less. Of course I do get occasional pixelation and freezing on some channels. I don't know if that's worst on the channels that are above 100.

    TWC can measure signal strengths but I've heard they only do it at a few different frequencies. I don't know if they can do anything to make them more uniform across all channels.

    Unless your cabling is new, it may pay to examine all cables, connectors and splitters that you can reach and replace any that might be old. I see posts where people say the cable co replaced splitters but I don't know if they did it for free or not. I think I'm responsible for the cabling inside my house but maybe not.

    Rather than looking at the signal levels, I would be looking at the RS Corrected and Uncorrected values. A lot of Uncorrected's could indicated a signal issue. If signal level is 100 but Uncorrected's hold at zero then all is well. Note that every time you change channels, the RS Statistics clear to zero. You can look at time since tune start to see how long of a period the RS stats 'covers'. My signal strengths run right at 100 or just a little under on my S3 and I have no problems (except for SDV channels but that is a different problem).
