The source for this audio capture was PAL, and suffered from the 4% pitch increase caused by PAL speedup. I am used to the correct pitch from watching my 1995 PAL VHS tapes (pitch corrected) and Dr Gonzo's DVDs. When I dug out this PAL recording I immediately noticed the pitch increase, and found it distracting. Personally I wouldn't choose to watch Star Wars this way.
Pitch correction attempts by Citizen, using PC audio editing software, apparently did not give good results. I have a lead on a method that might give better results, but have not tried it yet.
Playing it back at NTSC speed cancels out the speedup and restores the correct pitch. If - and I stress this is just speculation - the new PAL OOT DVDs are made from same masters as the French laserdiscs, then they will be a good starting point for making anamorphic NTSC DVDs. I can easily play NTSC format DVDs, as can most people who live in PAL countries. This would seem to be my preferred option at the moment.
