Looked over the '82 rental version and a later early Beta HiFi release, (pre '85) and they are different from the HBO version. No squeezed macrobinocular shots, and much different pan and scan in many shots. Just how many fullscreen transfers were there? I'm going to have to dust off my ancient LD version at this rate.

I contacted the guy who sold me my "new" beta, and apparently linear audio reproduction can vary quite a bit over all the models Sony made. So I may have to capture everything twice.

I might also try recording audio from the headphone jack, which is something I did once or twice back in college. Although I can't recall exactly why I needed to do it at the time. ;)
