I have been surprised to find that the Multiple stereo setting with my 5.1 system sounds louder, richer and fuller than the Pro Logic II Movie mode or any other setting with Blu-Rays, games, dvds, etc. Is this normal? What I'm hearing sounds great, but I guess I expected some sort of an improvement over multiple stereo with a true surround signal, not a decrease in sound quality. I find myself having to dramatically raise the volume whenever I switch from Multiple Stereo surround mode to Pro Logic II Movie or Music mode. The latter modes just sound thin, especially before raising the volume way higher than I have it on the multi-stereo mode.
