Advertisements This week's HD episode of 'Lost' recorded with sound, but without the voice track. I forwarded throughout the recording and everything was fine, surround sound audio was clear, picture quality was great, but there were no voices. I skipped throughout the recording and found that the audio/voice in the commercials were fine. Then I noticed that the receiver flipped between PCM & DolbyD and back to PCM when 'Lost' restarted. I don't recall anyone reporting this problem...I wonder if the problem was TWC, TiVo, or the Denon receiver. I'm guessing it was the way TWC broadcasted.
