It sounds heaps better, but sometimes I just wonder if its the loudness that tricks me into assuming its better... Why is PCM so much louder than Dolby 5.1?

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...

Through optical and from my PS3 to my receiver you can get 3.1 uncompressed. The center, fronts and sub are all active. It sounds great and on most movies it is 6.9 Kbps which is more than 10 times DD 5.1, but I like the surround sound so until I upgrade my receiver to one that is HDMI, I wil listen in DD 5.1.

It's from Dialog Normalization that is used in Dolby Digital. PCM and DTS do not use any form of dialog normalization.

It's not that. Dialnorm won't affect this amount of difference on the dynamics. there is clear compression being heard on a DD track.

And based on your settings on your receiver, it will apply pro-logic decoding on this 2ch downmix which is why you get audio from your center channel and your subwoofer is receiving a bass signal due to your bass management configuration.
