Advertisements I wanted to post here that my Tivo HD has audio dropouts problems when listening to any Dolby Digital audio source over optical. Probably 3-4 dropouts per hours. It's so frustrating that I had to switch the unit to PCM --- which fixes the problem. Of course, I'm pissed I have to give up the 5.1 sound on the channels that have it just to keep the dropouts from happening. They aren't recorded - instant replay and I'll hear the dropped audio. My stereo is a Sony STR-DE885 -- which has no problems with any of the other Dolby Digital devices including my old Motorola HD DVR. I would think if there were problems with the Tivo communicating to my receiver it would happen when it was sending a (higher bitrate) PCM 48Khz signal... I still have a little time to return the unit to Circuit City is anyone thinks this isn't normal. I just don't know what to do.
