Advertisements I have a 500GB Tivo Bolt VOX with Comcast Cable. Live TV is perfect, but during playback of recordings, at random intervals from 10 to 30 minutes apart, the playback video will pixelate for a couple seconds (audio is unaffected) and go back to normal. The odd part is that if I hit the Replay button and play back the exact same instance of the recording that just pixelated, it plays perfectly fine the second time with no pixelation at all. This happens to recordings made on multiple channels. I have two Tivo minis connected to this Bolt that do _not_ exhibit the same problem on playback. I have tested the Bolt on two different televisions with the same random pixelation results. I have tried attenuating the signal as suggested in other posts, but it's still occurring. Signal Strength: 87% SNR: 35dB. I've also done the basics: reseat the cable card, reboot the Tivo, check cables, etc. Any idea on what could be causing this strange behavior? Thanks!
