I'd just need to know which segments are missing. Fortunately they might be at moments where music/FX are not prominent (i.e., the reel change between Luke's training aboard the Millennium Falcon and Tarkin ordering Leia to be terminated). But then, if THAT is the case, then a dub from a 35mm Dolby source -- if there are no discernible differences in the FX or audio levels at those moments -- would be, acoustically, preferable to my open-air recording.

I'm also curious how the tracks were patched into the cassette deck: L and R alone? I presume he'd have skipped the boom tracks and the surround. Center? And was this on high bias or metal tape?

Also, the film is a few minutes above two hours, so is the final credit music cut off?
