Need some help. Looking to build a 7" PJ but I need a way of running without the computer on. I don't want to have to run the computer to watch DirecTV or VCR. N4, N5, and N6 support 852x480, but not 800x480 (the native resolution for the Lilliput 7"). Anyone try this out? Any suggestions?

*edit - I should clarify that I am trying to avoid using the video input on the lilliput because I don't want to stretch out the image.
