Simon is right, DVI can be digital or analog. I have one DVI connection on my Samsung DLP and I use it for my Samsung DVD player. I would like to buy a switch box and that way I could use the same DVI in for my 942 and DVD player, but the switch box I'd like to get is $250. So, I use the 1080i component inputs for my 942 and I get a very good picture...almost as good as my DVD picture quality, so I'm not complaining.
I plan on replacing my DLP set in about 2 years and at that point, I'll make sure that it has both HDMI and DVI inputs.
