Don't know if anyone else out there has (or is) experiencing my particular problem or whether I'm not reading my user manual properly - not hard considering its undecipherable at the best of times. Anyway, I'm experiencing sound problems on a few dvd's which manifests itself as a slight echo from the centre speaker. My dvd player is a Sony DVPS725 with an optical link to the amp. Affected (afflicted) dvd's are Sexy Beast (R2) and Cherry Falls (R2) so far. Additionally, I have a few R1 and R2 dvd's which have Dolby Digital soundtracks (according to the case notes - R1 Brainstorm being a good example) but the amp display shows them as Pro Logic, despite the DD led lighting up. And it sure sounds like plain old DPL to me. I've got the amp set up to auto sense the signal being fed to it but I don't know if these are dvd mastering problems, player problems or amp setup problems. Anyone out there had this problem fixed with a firmware upgrade or something?
