Advertisements This is exactly the same problem I'm having. Scanning through the rest of the thread, I'm not 100% certain that these are the same symptoms everyone else here is having. A lot of people seem to report that they've only seen the freeze when not watching live TV, whereas you and I are both seeing this on channel changes. For me the problem only occurred on non-HD channels. Flipping around the HD channels everything was fine, but if I went to the lower channels the majority of them (but not every one) would freeze up. For example, channel 5 would freeze consistently, but I could never get channel 4 to freeze, even after flipping back and forth numerous times. I also notice, when I change channels and the TiVo is behaving, that there is a slight jump in the video a moment after the new channel comes on... Almost as though the TiVo is considering whether to freeze the video, and decides not to do it this time... Another odd and possibly related thing I've seen is with the music channels: the music starts playing, and the screen is black for a moment. Then there is a brief "blip" in the music, the video kicks in, and the music kicks back in. Last night I also had two occurrences of stuttering live TV, with no effect on the audio. Both times I hit the quick replay button, then fast forwarded to catch back up with the live signal, and it fixed the problem.
