Just got a reply from Infocus for my X1 projector, and they tell me to don't waste any money by buying a DVD that upconvert via the DVI. The way it set up right now is as good as it get. Hey, I am still happy with my X1, I was just trying to squize the max from it. I guess I will wait 1 or 2 year and upgrade with a projector with a higher resolution. I got the brand new X1 for $1200 18 month ago; maybe if am luck again I could found a projector who have at less 1200X1200 resolution under $2K in 18 or 24 month.
Merry Christmas !
