Chewtobacca has already finished his NTSC DVD5 conversion. He used avisynth, so in terms of video, the results should be better than a user friendly app like that and the audio will be h_h's 5.1. I'm just downloading it and we are in testing stages but it should be available within a week. The download size is only 3.7GB, so I'll probably be adding one or two more audio mixes, if I figure out how to do it. But if anything, I'd be adding the monomix and the stereo mix, so that it has the complete 1977 audio mix range.
