    BTW, just checking back in here. It's been a few months. On the whole, the TA works when watching live. But recording off of switched video is basically a crap shoot. I'd say 50% is about the high water mark of success with this thing when Tivo has to tune its own switched channel. Most of the time it'll fail with a signal not available, but sometimes it just doesn't record chunks (15+ minutes) of signal, etc.

    On the whole, this thing has been beyond annoying. I hope others have had better luck, but I think it's coming close to time to kiss TW goodbye.

    Sorry to hear about your experience. Fortunately, my experience has been very good. Have you checked your RDC and FDC signal levels (in dBmV) in TA Diags? (go into TA Diags and hit select twice... mid way down the page) If you are having tuning issues, you may be having signal issues in the communicatoins path between the hub and the TA.

    FDC is -6 dBmv and RDC is 46 dBmv ... not sure what range I'm looking for?

    In any event, as I said, I'm not sure how much of a signal problem it is. If I watch live, it's usually fine (some pixelation, usually in bursts). But if Tivo is left to record on its own, that's when the majority of problems occur. This to mean seems as if it has problems communicating with the device perhaps? I guess it could be a problem sending upstream, but wouldn't that manifest when I changed channels manually as well?

    Edit to add, tuner is showing +3 dBmv

    Those signal values are fine.

    The pixelation on SDV channels is a known issue which TWC is working on. You will probably see that the RS Uncorrected value remains 0 even though you see pixelation.

    Yes, this is correct. If I watch live and get pixelation, the RS Corrected increases, but not uncorrected.

    So the question to me is still why Tivo will periodically just fail to record with a "Signal not available" in the history. Just to give sequence properly, it usually goes like this:

    * Set Tivo to record FXHD @ 9:00
    * Tivo attempts to tape FXHD @ 9:00 ... if you attempt to watch this recording, it's just a black screen
    * At 10:00, Tivo removes recording, adds the "signal not available" message to recording history
    * At 10:01 (or if you stop the recording prematurely), you can tune FXHD via Live TV just fine ... and if you start recording manually at this point it'll pick it up properly from there (but not with the missed portion).

    What's going wrong in the chain of Tivo events? I've never seen an instance where I manually tune a channel and then the channel is blank, so to me this indicates that Tivo's tuning mechanism is different when it's doing so for a recording.

    I admittedly have a small # of data points. Mostly I record Rescue Me on FXHD and MythBusters on DISCHD. Both are subject to about 50% "signal not available". This week FXHD was fine (albeit pixelated for a lot of the episode), and DISCHD was intermittent (first 15 minutes no signal, last 7 minutes no signal). Last week, DISCHD was 100% fine (no pixelation even), but FXHD was "no signal". In that same time period, I watched the Canes (Versus HD) live and had minor pixelation issues, but never attempted to record it.

    When you get a 'black screen' situation... pop into DVR Diags and you will likely find Signal Lock = No and Program Lock = No for that tuner. This is indicating that the stream wasnt found. If I can ever catch another one... I would note the frequency nd PID's and retune the channel and compare to see if one was incorrect. I can only speculate that the SDV system was slow in getting the stream in place and TiVo gave up on the tune operation... only a guess though..

    Well, that's the thing. If I tune manually I cannot reproduce this. Even if I cancel Tivo's recording of blank screen, it apparently retunes. I guess it's possible Tivo "gives up" earlier on an automatic tune as compared to a manual tune.

    That's pretty bizarre. As you say, your symptoms would seem to suggest that the method used to tune for live TV is somehow different than the method used to tune for a recording. The only other possibility I can think of is that maybe the Tivo has a much higher error threshold for live TV for some reason. In other words, maybe a level of pixelation that is acceptable in live TV, is considered unacceptable for recordings. I realize that even live TV is being recorded for the buffer, etc, but maybe actual commanded recordings have a lower acceptable error rate. if you do the tests that SCSIRAID indicated and the channels IS tuned and locked and the recording is still black, then maybe the Tivo is simply discarding the entire signal for recording purposes because it doesn't meet the required quality standard.
    This is all speculation, obviously. Just food for thought.

    Is it possible there is a "flag" of some sort that interferes with the recording process coming from TWC. Like szurlo said, it is actually being recorded on the drive all the time, but when it is, whats the term "saved" that Tivo then has issues. I still believe 99% of all problems originate from TWC anyway. Do you think TWC really is going to give a rats@$$ about our TA issues when we don't generate them any revenue for it and DO cause them problems with our constant complaints about our worthless TIVOs. ;)

    Here in Raleigh, TWC Engineering has shown me that they definitely care about their product and its interaction with TiVo. They have been working with me for quite some time on the SDV pixelation issue. They have spent a significant amount of time and energy with me on this.

    Hi all...

    New to the forum. I'm currently with TWC in Charlotte and have been thinking about moving to Tivo for about a week now. I've read about the need for tuning adapters with switched channels. In a live chat last week, the rep wouldn't tell me what channels were switched. I asked a couple of times and then he finally said they didn't have a list. Seriously? TWC doesn't have a list of channels that are switched? He said the only way to get the tuning adapter was to order them online, but he couldn't tell me if they were available. I ended up calling right after the rep I got said they were available but to order them online. The online form still said "pre-order" which didn't make me feel good. After filling out the form, it just said they'll contact me when they're available.

    The TA is the only thing holding me back right now. Sounds like there are some issues with them as well but I'm willing to make the jump whenever TWC decides to send them out.

    I'm in South Charlotte and got my TA 3 weeks ago after waiting for 3 weeks. Apparently they've received a shipment and are working down the list now. Having said that, all worked fine for about 2 weeks but now I'm getting frozen a number of channels. 90% of channels work fine but most problems deal with PlanetGreen, History, FSC and SciFi.

    I've had two techs out over the past three days and they've adjusted the signal but still no luck. Another one tomorrow morning. Apparently they're going to adjust or "update" the Cablecard dynamically and need a TWC tech nearby, just in case. They tried that this morning at 8:30 but the folks on the Cablecard team don't start their day until 10am so another try for tomorrow.

    Got my Tivo a few weeks ago, TWC installed Cable Card shortly there after. Then I turned around and called TWC about getting a Tuning Adapter and they insisted on setting up a dispatch for Saturday, May 23, though I knew the TA is a home owner installed box I figured what the heck.

    Saturday came and no TWC tech. An hour after the maintenance window I called TWC and asked not only where my tech was but why no one communicated with me. They were very humble, gave me a $20 credit and said that they would dispatch on Monday, May 25th.

    On Monday, an hour into my maintenance window TWC telephoned me to explain that the TA was a home owner installed box and that they would order for me since the Web site to order stated that I was not entitled to order one.

    On Friday, May 29, I tried the Web site and this time it allowed me to successfully order a TA.

    Today, Tuesday, June 2, I telephoned TWC and asked where my TA was, the one supposedly ordered on May 25. After two representatives and several minutes of hold time I was informed that all shipments of the TA have been suspended due to software issues and they would notify me when they once again become available.

    Can anyone confirm the status and/or availability of TA in the Raleigh area.

    Thank You

    I was missing FoodHD on my downstairs TA but my upstairs TA was fine. It took several reboots of all devices and then it started to tune. Also, there have been many occasions when I fire up the TV and Im frozen on channel 17 (Cartoon Network I think) as my kids like that channel. Just hit live TV and it works. No issues recording thus far and I do record FoodTV pretty routinely. TWC still has some fine tuning to do. Maybe we should all ditch our TiVos and cable providers and just use Hulu. I’m hanging in there. :D

    While I am awaiting my TA and the challenges it will provide, my only comment to anyone having any kind of challenges with TWC, such as yourself, is that we have to wait until June 13th to see what new challenges await us after the digital cut over.

    Cheers

    Yeah, I routinely find a frozen picture on the screen when I turn on the TV if the last channel tuned was SDV. I'm assuming the stream was dropped by the head end due to no one actively watching it and for some reason the Tivo just goes out into la-la land when that happens.

    So tonight again, Mythbusters failed to tune on DISCHD, but I caught it in the act. Tried to pop into DVR diagnostics to see if there's a lock, etc. and Tivo displays the "Please Wait" screen. Seems like I can't get out of it. Recordings that were supposed to stop at 10:00 did so (by the lights anyway), but nothing will get me out of please wait...

    Edit to add: Unplugging the TA's USB caused Tivo to bail from the DVR diag screen. Back to live TV and now DISCHD is tuned fine.

    Argh.

    Are you using an S3 or a THD? Ive never seen a 'please wait' screen on my S3. What does TA diags show for RDC and FDC signal strength (or did I ask you that already/)

    EDIT: I see that I asked that already and your values are fine...

    I've seen that once but after sitting at "Pleas Wait" for a while, the TiVo spontaneously rebooted. That was the only time it had done that after I got rid of the expander and replaced the drive with a 1TB instead.
