Since you´re using optical, you only get the "core" from DTS-HD MA (core is "DTS - 1.5 Mbps") and Dolby TrueHD (core is "Dolby Digital - 640kbps", I believe?). So use bitstream.
Thanx, i appreciate the reply. So when the ps3 says choosing bitstream may leave out some audio, i should just ignore that in my situation. Also when i transfer cd's to my ps3 what format should i use AAC, MP3
