I'll second the request. I know it kinda "defeats the purpose" of the project to downconvert it to SD, but it would nonetheless be nice to have a good, colour-corrected, non-2004-Emperor version of ESB to watch until ESB:R comes out. (I speak, of course, as one without an HD TV or blue-ray player; obviously, this exercise would be pointless otherwise.)
I know negative1 mentioned he'd managed to do it using a program called AlltoAVI. I tried it out and made a little headway, but my efforts were ultimately fruitless. So if anyone has any suggestions on how to downconvert this puppy, it'd certainly be appreciated by some of us HD-deprived sods. :)
