I've read several posts about the 2 and have seen conflicting info. Here is my situation: I have a 4 year old Toshiba DVD player that has an optical output that I am using. I just bought a nice Onkyo receiver (TX-NR900) that supports practically every format out there. If I want the best quality sound out of my DTS and Dolby Digital DVD movies, what do I set my Toshiba DVD player to output the audio?? Bitstream or PCM? Thanks.
