Hey guys- i've been a Tivo man for 5 days now. Had been 100% awesome until last night. One channel via Verizon FIOS - Comcast Sportsnet Philly HD - Channel 829 in my area - started breaking up like crazy last night. I knew it was more than the "macroblocking" problem. Anyway - I checked the diagnostics - the signal level would go from 100 - to 80 - to 67 - back to 100 - and the SNR was moving all over from 38dB to 34dB to 31dB - with alot of noticeable errors. It never did this at all since I got hooked up Monday (I had watched a few Phils games during the week) Doing the same thing on Tuner 2 - so ruled out the cable card. Funny thing is - it's not doing it on my other Verizon provided cable boxes in the house - their signal levels were constant. I haven't noticed it on any other channel yet - so i'm not sure what to think. Anyone else see this before? I removed the line from the splitter - hooked it back up - no change. Thanks for any tips.
