I just bought a Kenwood HBT-S500 (which includes a KAF-S500-Amplifier + 4 boxes + 1 SW). I have this System connected to my Pioneer DVD-Player DV-464-S (192KHz, 24bitDAC) via a fiber-optical-cable. When I listen to Music-CDs I CAN select nice Listening-Modes such as: Movie, Music , Pro Logic, Cinema, Music, Arena, Jazz-Club, Stadium, Disco, Theater... When I watch Movie-DVDs (e.g. DVD: Dolby Digital, DTS, 5.1ch surround) I DON'T have all these "Listen-Modes" available anymore. I only have 2 Listen Modes: "Stereo" and "Dolby-D" and the quality is much much worse then playing Music-CDs with all Listen-Modes! :-( Please let me know why is that? The sound from Movies is thus very different (worse) then listing to Music-CDs. If I switch on my DVD-Player "Dolby Digital > PCM" I now can select on the Kenwood-Amplifier all the Listen-Modes, but the Audio-quality might dropped? What is the problem? Please help me!!
