Is it possible to get uncompressed PCM over optical? I was wondering why the bass was so poor on both of these movies until I put them in Dolby 5.1 mode. Could this be some setting on my receiver?
The only way (to the best of my knowledge) to get any advanced audio; this includes Dolby True HD, PCM uncompressed, etc... is to use HDMI or analog cables. You can NOT get uncompressed sound via optical as there is not enough "room" for the large signal to transmit.
Someone feel free to correct me if I am wrong, but this is what my understanding is.
As for the difference in sound... I just watched Dreamgirls (HD DVD) and then Apocalypto (BD) and Batman Begins (HD DVD) and both Batman and Apocalypto DESTROYED Dreamgirls' DD+ soundtrack.
I hadn't really appreciated the difference uncompressed sound offered, but upon watching these discs, it was apparent that Dreamgirls sounded a bit anemic in comparison.
I was disappointed, too; I was expecting a walloping soundtrack on that film, being a musical and all...
