....does it sometimes feel as if some DVDs, if not almost all, do not demonstrate a genuine immersive, room-filling experience when played back on moderately powered systems for small or medium sized rooms? I guess what I am trying to get at is this...most of the time, when I play back DVDs in surround, and there arent wild action sequences going on, I can have a comfortable conversation with the person next to me on the couch, even with dialogue going on...sometimes I feel like a simple center channel speaker just isnt enough to immerse me in a film's dialogue or on-screen action; and this is with my receiver turned up PAST the "50" value on the volume screen (Onkyo receiver owners will know what Im talking about). I was watching Finding Nemo yesterday afternoon, and while its Dolby Digital EX soundtrack was delightful, when there wasnt any animated action going on, my apartment wasnt "filled with sound" even when dialogue was firing from the center channel, and this was with the receiver turned up...is this normal? Are we SUPPOSED to be able to talk over dialogue and some front soundstage activity from the sweet spot, even if the volume is turned up? Of course, when action is ripping across all channels, or an intense DTS disc is doing its thing, talking over such action is difficult; but during quieter moments, is this normal in a home theater, where the room seems VERY quiet even though dialogue is coming from a center channel speaker?
