I made a PAL ROTJ-synced 1983 LD track, but frankly I wouldn't trust it to be anything but a rough guide--my work is a little on the amateur side. Oh, and I made a PAL-adjusted 5.1 track based on hairy_hen's. That might be better, as the amateur stuff is limited to the frames I edited.

EDIT: Also, I believe Laserschwert found that the official ROTJ PAL track had been re-ADR'd, so the sound effects lined up perfectly with NTSC once you made the frames match, but the dialogue drifted slightly in and out of sync. Weird. I don't think there's any need to re-create that.
