Listening to the synced tracks, so far so good. In fact I'm pretty sure I'm going to toss out my own syncs of the ROTJ stereo mixes in favor of yours. Also planning to give the SW 85 and 93 mixes a listen, and the ESB 93 mix, will likely have more feedback later.
Also, FWIW, future preservations of ROTJ are switching frame references from PAL to NTSC (yeah I know, don't blame me). Which means your ROTJ tracks sync just fine with everything right now, but they'll need modifications for DeEdv2 and Team Blu, etc. No big deal--I actually made some quick and dirty NTSC-synced versions from your PAL versions for just this purpose--but I wanted to give some warning.
