Just pointing out: you don't need the HD versions to make an HD split-screen.

Assuming the DVDs you are using are PAL and anamorphic, and the AR is approx 2.35:1, that means the active picture area is 720 x (guessing) 436.

Correcting for the anamorphic squeeze gives you 1024 x 436, or 720 x 306, depending on whether you scale the horizontal or vertical.

These sizes are not far off the 960 x 408 or 640 x 272 you would need to make a 2-by-2 1080p or 720p version respectively.

But of course, most people would be happy with a standard DVD version...
