I have a decent sized DVD collection, to put it mildly, and am not ready to jump onto the HD-DVD/Blu-Ray bandwagon. With the recent LCD HDTV I purchased, I managed to get a standard DVD player that upconverts the image to 1080i via an HDMI cable and have been quite impressed with the sharpness of the image from regular DVD-- of course if a DVD looks grainy on a regular TV, it tends to look more so on a HDTV.

I'll admit not to have seen a demo in-person of DVD VS either of the High-Def format, but I understand the difference isn't as big of a leap as DVD was over VHS.
