    My HDVR2 has been acting up, lots of incomplete recordings and glitches. I pulled the hard drive and ran the full diagnostics on it, it's fine.

    Turns out doing a signal test that the even transponders on the 2nd tuner either don't show up (while they are fine on the 1st tuner), or bounce between a good signal and 0.

    I swapped cables between tuner 1 and tuner 2, but the problem stays on tuner 2. I have done a clear and delete all, but that hasn't helped. I guess I could tell the HDVR2 that I only have one tuner, since this is a backup unit and I can live without 2 tuners. However, I'd really like to have the 2-tuner functionality.

    Is there anything else I can check? I swapped the cables both at the wall and on the back of the TiVo, so I can pretty safely rule out the cables or multiswitch/dish I would think.

    There has been reported a problem with that TiVo where the use of the s-video output messes up tuner 2. If you are using the s-video, try the composite instead.

    I'm having the same problem :( . What is the reported problem? who is doing the reporting of the problem, D TV? TIVO or other customers? Help this is driving me nuts.

    Thanks :)

    Oh now that's weird! I tested yesterday by placing the SD Tivo (the one with the problems) where my HR10-250 is. Problem went away! I figured it was bad cabling perhaps, but that didn't explain why the problem stayed on Tuner #2 eve with the cables swapped.

    However, when I swapped it with the HR10-250, I use composite cables only. When the bad TiVo is in its regular place, I am using both S-Video and both composite outs. I will go ahead and remove the S-Video and see if that straightens mine out as well.


    Well, that's what it is apparently. Actually doesn't matter if it's S-Video or not, if I have more than one of the A/V connections active the signal strength on the 2nd tuner on even transponders really goes nuts. If I drop down to one connection it's almost stable, only get a drop on the 2nd tuner every 30-45 seconds, rather than alternating good/bad as it does with multiple connections.

    However, even dropouts every 45 seconds isn't acceptable. I guess this might be a sign that the power supply is going out, since removing some load seems to alleviate the problem? As much as I hate to do it, I may just tell it I only have 1 tuner and let it go for now. I don't want to spend much money on fixing this thing, and if it'll keep running on 1 tuner I suppose that's better than nothing.
