I have had this Tivo for about 8 months, everything was working perfect until about 2 months ago. My FoxHD station is 410, my CBSHD station is 405. It started with just the cbs station first. Would be watching it, and then it would look like it was pixelating. It would freeze, then pixelate a little then freeze. I would have to switch to the analog cbs, 05, to finish watching the show. Also, I have another TV using a cable tuner box, and a 2nd using a cable TV DVR. I would check both of those TVs when this happened, and they would be fine, no issues at all. Then, FoxHD station started doing the same thing, everything would be fine, then boom, it would start pixelating, freezing, etc, just like CBS. These are the only two channels I have noticed it happening on, not to say it doesn't happen on any other channel, but I haven't caught it happening on any other channel. Of course, this TV has Lifetime Subscription on it, and the last series 2 dual tuner I had, also had lifetime sub on it. The series 2 also has gone bad, needing a power supply from what I can figure. As bad as cable DVRs are, I think from now on I'll not be buying any more Tivo's, as this is getting too costly and aggravating to own them. Anyhow, would anyone have any idea as to what is causing this freezing, pixelating - and why is it only happening on 2 channels?
