WOW this is really coming together, I wish I could be of more help but my current setup isn’t ideal for editing the best I could do is offer some tips about the 20th anniversary version and give links or info if I find anything new, so to sum it up so far we have
at least 2 different confirmed 720p hdtv rips of the 20th anniversary version (hopefully widescreen)
we need access to a blu ray rip of the 1982 version (a 720p rip for consistent quality between both sources, unless it can be up converted to 1080p somehow)
a list of changes between the 20th anniversary and original theatrical cut
access to the DTS and Dolby audio tracks
something just occurred to me if the 20th anniversary version is in 720p and the only differences are two extra scenes with the rest being altered shots is a blu ray rip needed since the blu ray is exactly the same minus the digital alterations couldn’t the 720p rip just be synced up with the DTS and Dolby tracks and be made available, unless of course if someone else has a better idea
did I miss anything ?
