Do you use an a/v receiver? I use a denon 1804 which has 2 component inputs and one out so that solves the problem of only one component input on the monitor for my hd and dvd. For some stupid reason adelphia cable doesn't support dvi yet. If you dont use a receiver its a good excuse to get into the hobby and using hdtv you'll want to take advantage of dolby digital with high definition. I haven't had any resolution issues by using component for hd.
