I'm new here guys, but here's my problem: I have the cambridge ddt2500 desktop digital setup. I've got my dvd player hooked up via digital input. It all works fine, except sometimes when i skip around chapters, or fast forward/review, the sound doesn't come on. It still indicates that Dolby Digital is being detected, but it doesn't play anything. I mess around wiht the "audio mode" button for a little, till I get to stereo, then it kicks in via stereo. Press audio again, and its back in Dolby Digital. Anyone else have a similar problem?
