I finally got the Primitive Screwhead edition downloaded and I have to say, nice work Ridgeshark!

The extra scenes are cleaned up really nicely. As far as the aspect ratios, I woudn't worry too much about them considering what a mess the actual film print was. I worked at a movie theater that showed the film when it was first released and I got to see the film itself. It was originally mostly open matte and intended to be shown at 1.66:1 aspect ratio but composed to still work if the projectionist misframed it for 1.85:1. I say mostly open matte because, while a lot of frames had information over the entire frame, some of them had artificial matte bars or other wierd stuff that was intended to be matted out. The US laserdisc version got it mostly right but had a few mis-framed shots and the Japanese laserdisc left it open matte and tried to pan-and-scan the frames with matte bars or other garbage at the top and/or bottom. The DVDs and blu-rays all crop the footage down to 1.78:1 or 1.85:1.

I'm currently in the process of trying to upscale my R3 DVD to 720p. If that works well, I've been considering combining that with the Blu-Ray footage to create an HD version of the R3 Director's Cut. I don't know how that will work out, though.
