I viewed a variety of DVDs, including Gladiator (compared this one to an odd 35mm reel of the film version and the video gear feared quite well, though it was clearly deficient in the gray scale department; the 5500 needs to be calibrated to address such factors as correct color temperature -the image was too blue by comparison with the film sample- etc.), Superbit The Fifth Element (not a perfect transfer by any means!), Toy Story 2, and an Academy Awards DVD screener of Monsters, Inc. (the last two looked perfect! No EE...no artifacts of any kind...simply, incredibly, stunningly amazing!), Shrek, Ben-Hur, Lawrence Of Arabia and many more...
"I have a G11 with Rock+. Good transfers look stunning on it (at 11 ft wide!), while poor transfers look grainy, etc. While the picture is great in completely controlled situations, I am seriously considering upgrading to the G15 for increased light tolerance. All this talk about DVI has me wondering if this is the thing to do."
Well, your system is doing what is supposed to: resolve high and poor quality in the signal source! Yet the DVI route will exhibit greater accuracy in my opinion...
"Did you view any relatively bad transfers? I'm probably reflecting my lack of understanding here, but how does DVI improve the quality of a crappy transfer? Or is so much lost in the D->A, A->D that anything is just humorously improved with DVI?"
I didn't say DVI improves anything in the source, just that it resolves the video signal content more accurately, so great transfers will look even better while poor ones, well...will look even worse.
I think there is a definite loss occurring in the D-A, A-D process, so using DVI "cleans" things up (like if layers of sheer gauze have been lifted away)to a degree that the signal content can be displayed more accurately; we then can really see what the signal actually looks in its finished form...good, bad, of indifferent. Hope this helps...
