"Because of its exceptional performance and quality, Advanced Audio Coding (AAC) is at the core of the MPEG-4, 3GPP and 3GPP2 specifications and is the audio codec of choice for Internet, wireless and digital broadcast arenas. AAC provides audio encoding that compresses much more efficiently than older formats, such as MP3, yet delivers quality rivaling that of uncompressed CD audio."
Im thinking it has conflicting problems when using bitstream and something else for BD's. Thats just a guess.
I got a $400 TV, HD but not 1080p. Its pretty big, 30 something flat panel wide screen.
