I'm actually in the process of building some hybrid DVDs of the 97 SEs. So far I've got ANH nearly done, using the crawl and unsubtitled scenes from the TB release and the rest of the film from the GKar. The GKar is by far the best in terms of quality, but the subs are hard coded and can't be easily removed, so I've intercut sections from the TB to remove them. I've also converted them to NTSC since although PAL has a higher res, I can't STAND the 4% speed up (and I'm from Australia, where PAL is the standard :P!)

By the way, if anyone can point me in the direction of some 5.1 ac3s of the 97SE audio tracks, I'd be very grateful (assuming any exist). All I've got at the moment are the English audio tracks from the GKar and TB, which are Stereo only.
