odd chris. i've had none of those issues while watching the same movies. maybe you got a bogus unit. i am jealous of you having it hooked up to a dlp - talk about a rockin' pic!
it seems that dvi is really only a factor with fixed-pixel displays. with regular crt's, you still have that final analog conversion...so i'm not even sure if there is a worth-while gain? finally, remember that some dvi inputs (like the samsung) only output 1080i to a hdcp compliant dvi...
i hear ya andrew. check out this extensive thread over at avsforum. they compare the two major players in this area. pretty much left me with a "better decide for myself attitude". :) Bravo D1 vs. Samsung 931
