Good luck getting the DVI output to work even if you tried it with an NVIDIA card. Nobody here has reported any success yet at doing DVI at 1080i. However, you can do it over component output, but you probably have to buy something like the audio authority VGA->Component adapter, which I did. The reason I say this is that S-video and NTSC are still just 480i, ie. interlaced. EDTV, which is what a DVD puts out, is 720x480p. Now in theory, there is no reason why 480i shouldn't be able to give you everything on a DVD, since a DVD comes at 24 frames per second and every frame is shown 2 or 3 times, so all 480 lines should come in an interlace. But for some reason it often does look better in many cases, with a nice anamorphic widescreen DVD. Sadly, with progressive scan DVD players so cheap -- cheaper than tha vga -> component adapter -- you might go that route in the meantime. However, the vga -> component is what you need to do all your TV from your mythbox to your HDTV in a progressive format. If nothing else you text, computer output, web surfing etc will look vastly better than over svideo.
