I am well underway with the ROTJ mixes, and the PAL audio is definitely different than the NTSC when framerate adjusted, so as far as I can tell it is the best sync reference I can find. The ESB mixes are done I think. There are minor niggles I have with these, but most of them are problems inherent in the mixes. After repatching I think that the 'Faces' version of the 93 mix is not as good as the 'Definitive Collection' version, so that will likely be my candidate for the 93 mix. The 85 mix versions are also hard to tell apart, but I am leaning towards the Japanese Special Collection version over the Special Widescreen Edition version of that mix. I have been thinking about putting together lossless isolated score mixes, but the only lossless/uncompressed source is the ISOSCORE of Belbucus', which has film audio over the cue fade outs in the score. Additionally I think any work towards using CD sources is another undertaking entirely to what I am trying to do here. Anyway, a bit more progress with ROTJ and I will send out a test/evaluation version of the theatrical mix.
