... huh? I don't think that's possible, unless you're talking about doing it in software, and even then I didn't think the xbox had the necessary computing power to do that ...
anyone, looks like MS made a really dumb decision again, this time about their internal scaler / output. Sometimes I just don't understand why they do the things they do ...
God, HDMI offers no increase in quality over any analog connection. Please people, try and understand that. The reason that MS won't upconvert DVDs is because the movie studios are forcing everyone who outputs any movie signal in Hi-Def, be it from an HD source (HD-DVD, Blu-Ray) or an upconverted DVD, to be copy-protected with HDCP, which only works on digital connections (HDMI / DVI). Because of that, if MS doesn't support digital outputs (which it sounds like they won't), then they won't be able to upconvert DVDs (unless you mod it, and then someone might be able to get it to upconvert DVDs over component that way, which is technically illegal anyway).
