hi all - last night i was watching 'shadow of the vampire' (btw - not a bad flick). when i went into the language selection and chose the dts option, it attempted to play a short clip to "demo" the dts sound. instead, i heard no sound whatsoever. i've double-checked my sony's dvp-560d's settings, and everything looks good. i'm running the 5.1 outputs from the dvd into my onkyo tx-sv646 - then selecting the multi-ch input there. when i selected the dd option, i heard sound. so...i guess my system isn't capable of producing dts? aarggh!  i should mention, on my other dvd's, this doesn't occur. i can choose the dts option, and everything appears to work fine.
