    THD, not a series 3.

    If I had to make a guess, it was like Tivo couldn't communicate with the TA (I assume it does this in the DVR diags) and just hung up trying. When the TA was unplugged, it got an interrupt and bailed (showing the "TA has been disconnected" screen popup).

    I've had Tivo reboot spontaneously once or twice in spots like that, but never from the DVR Diag screen. Drive is original, no expander, etc. In general the unit is stable, no signs of drive trouble, etc.

    Yes... I would tend to agree. They may have been in the middle of a command exchange such as TiVo asking TA to resolve a channel frequency and the command hung or communications was lost. I would expect TiVo would have a recovery process for that but aparrently not. Just for grins you might try a new USB cable and see if that helps.

    This would make some sense. At 9:00 it issued the command, but it never responded (hence the black screen record) and it just sits there. I'll try a new USB cable, but I wonder if this is something the Tivo support folks can help with? Do they even provide support for the TA?

    So the crux of the problem was an exposed cable and water damage to the outside hub. According to the last TWC tech (Kenny), whoever closed the box last time (the box was locked by TWC) nicked the cable and left sufficient room for water to settle in. The guy ran a temporary cable and without resetting the TA or Tivo all signals are coming in perfect. Now waiting for the maintenance crew to bury the cable. Good job Kenny!

    Just had TA installed yesterday, and it's not working. Not sure what the problem is but here are some of the items I've seen discussed on this thread:

    -I have solid green light on the TA (after calling in to TWC)
    Tuning Resolver in TA Diags:
    -Authorized: Yes
    -OpStatus: Ready
    DVR Diags:
    -Signal strength = 43 (too low?)
    -SNR: 28dB
    -RS Uncorrected: 0
    -RS Corrected: 372000 and counting

    Any help would be greatly appreciated!!!

    Wow... signal strength is way too low.... SNR should be in the 33-36 range. Suggest you try a different cable between TA and TiVo.... You can also go into TA Diags and look for the signal strength page and get their numbers.

    I guess I should join the TA happiness club. I installed mine this afternoon. TiVo was happy but alas no new channels. I called TWC to enable on my account and was told that I could only have basic cable with TiVo, TA, and Cable Card. I insisted they were wrong and got transferred to a technical support group in Charlotte. I was advised to restart the TiVo (hmmm ... same fix as TWC DVR) which I did but still have same symptom. Got transferred to Raleigh help desk and a Cable Card technician will be here Saturday afternoon.

    Oh, by the way my signal is 44db and I get basic cable great, even the network channels in HD.

    I believe both of our problems are caused by TWC having their only technical guy on vacation.

    Cheers

    I have a feeling you are going to find that the first person was correct. You have to subscribe to Digital cable in order to get the Digital channels and all Digipic packages include a TWC Digital box... The fix is pretty simple though... you get a Digipic package and put the TW box in the closet or use it as a doorstop. :D

    The only problem that I have with doing that is that every time I telephone TWC I get different information. I expect consistent, accurate information every time and if they do not know the answer, they should say so.

    Understand.... However, whenever you mention cablecards or TiVo's to most CSR's their eyes glaze over.... Not making excuses though... Your expectations are reasonable but unfortunately not currently the normal occurance.

    ;)

    I have several challenges with TWC recently involving my installing a TiVo and trying to restore my level of view to where it had been with the TWC DVR. Cable Card install went okay, but I was left with basic channels. I finally installed the TA this afternoon, but alas basic channels even after 45 minutes on the phone with three different TWC resources. A tech was scheduled to be dispatched tomorrow. However, a guardian angel from TWC contacted me for further information regarding my account with TWC. Within an hour I received a telephone call to check my channels. Low and behold, a miracle, all my channels have been restored.

    Something else was restored. My faith in TWC.

    Thank you David and your manager David.

    Same here out near Fuquay-Varina.
    Pixelation/Freeze issues on many SDV Channels with no RS Corrected/Uncorrected so issue seems to come from headend unit.
    Next is a sweep of the area by TWC.

    If anybody else is having this issue (Pixelations on SDV channels ONLY, RS Uncorrected remains 0).... please drop me a PM. TWC is asking for more data. The kind of info that would be helpful would be things like:

    - What channels do you see them?
    - What is your 'service group' (from TA Diags) or your basic location (like town and subdivision).
    - Is there any time that they are more prevalent.
    - Is there any correlation to time such as the top and bottom of the hour
    - If you are watching Live... what is RS Corrected and Uncorrected values after you see them
    - SNR and Signal Strength
    - Show Title, Time, channel and time index into show
    - S3 or THD?

    TWC has TiVo's deployed on several service groups and are trying to figure out what is going on. Ive been doing parallel recordings on an 8300HDC which does NOT exhibit the problem. A lot of recording of 'Time Warp' , 'Mythbusters' and 'Deadliest Catch' are being done. If anybody is motivated to record those shows and report glitches it would be appreciated.

    See in BOLD above.
    I'm going to be away from home for a week.
    Local TWC replaced TA yesterday.
    Saw break up on TLD-HD about 9pm last night but no corresponding RS Corrected or Uncorrected.
    Have 20dB attenuator which has reduced the errors but hasn't stopped break up on SDV channels.
    I will give a more comprehensive answer to your list above when I get home next weekend.

    When I had an 8300HDC, I got Pixelation issues on the SDV channels and even frozen screens. Now that I got the TiVo up and running, same symptoms. So I believe it is not associated with the viewer terminating units. (Understand that I have been in the technical troubleshooting business for decades)

    The issues appear their worst when you would expect a lot of viewers, evenings and weekends. And one channel worst than another depending on the number of viewers of that channel as well as when viewers join a program. The latter seems to be the most logical issue because the viewer's device has to tell TWC that it wants to join the video data stream, the additional bandwidth required by the TWC head end device to honor that request causes the video data stream to experience 'sync slip' with the packets causing what appears to the viewer as Pixelation or gaps in sound. When the 'sync slip' gets real bad the viewer's device freezes the frame.

    If there were cable error or signal quality issues local to the viewer, every SDV channel and all the others would experience problems.

    I highly suspect that real problem is associated with capacity. Either the TWC sending unit is overwhelmed or the network is. The vendor providing TWC with equipment should be able provide diagnostic services that would be able to pin point the issue. Swapping gear or power cycling is not always the answer.

    Just my humble opinion.

    The SDV communications with the hub is done out of band from the video. The transport stream from the hub is not changed when viewers join an existing 'program'. If the new viewer requests a channel that is not already on a transport stream, the new program stream is multiplexed into the transport stream seamlessly.

    The issue you describe is different from what we are attempting to figure out. My issue is TiVo pixelation events on SDV only. Linear channels are fine. TiVo does not indicate any Forward Error Correction events which could signal RF issues. The 8300 does not exhibit the issue on exactly the same material.

    The issue you describe sounds more like an RF issue. You could go into TiVo diags and check the tuner stats to verify.

    You do not have to get the TWC box when subscribing to digital cable. You may have to go through multiple reps or a manager, but you can get them to remove the cost of the box from the digital cable package. I believe it subtracts around $9-$10 from the cost of digipac(which I think has been renamed to digital cable).

    I am not going to argue the point since I don't know the specifics of the Cisco IPTV solution that TWC has implemented.

    However, I still believe the issues for SDV are cause by sync slippage of the packet. Especially when everyone is experiencing the issue to one degree or another but only with SDV. To single out the RF is basically stating that the TWC physical network to the viewer is in need of overhaul or replacement.

    Still, you and I only agree to disagree and that is wrong for this forum. We need to seek the truth and the best way to do that is to provide the information you asked for and hope that TWC can use it to identify and resolve. I will provide my information in the next day or so.

    Cheers
