In the beginning, I found it difficult to work with the materials I had, because my computer was a 700 MHz Celeron with 64 MB RAM running Windows 2000 (you may have heard my laments about the pitiful state my computer was in)... I'm using a 2.0 GHz Sempron64 with 512 MB RAM and Ubuntu Linux (somewhat customized to be more efficient with that 512 MB), so working on the project became a lot easier.
The video track I have at this time, is from the LE R1 bonus disc (your GOUT), and the Greedo subtitles have been reformatted for the best match to what I'm familiar with. I don't know exactly how they looked in 1977, this is based on my recollections of VHS versions and EditDroid's subs.
The audio track I am currently using is a composite. Top priority is to the 1985 UK TV capture, then to the CED, then finally to an audio track salvaged from an encode of Dr. Gonzo's DVD (1993 LD). I plan to replace this if a better track comes along.
I am currently also using the LE R1 AC3 as "the 2.0", not sure if it is or not, it's certainly not the mix I've heard on the VHSes, nor ROW47, and afaict matches details of both the 2.0 and DE, neither of which I can tell apart atm.
Most likely, I'll offer this as an OGM, and it will be possible to isolate the audio tracks, ac3 them and mux them onto vobbage if need be.
