I have an HBO airing on an old Betamax tape, but the recording was started after the famous flying logo in space opening that would complete the experience. I also have a second Beta tape that was recorded from a different cable outlet at the same time, but apparently from the same master.

According to one source I can't find right now, the HBO version is sourced from 16mm and has different pan and scan from the CBS/Fox video master. The one telltale sign is Luke's binocular screen display when he's spying on the sandpeople is squeezed.

I would love to see this preserved as well. My Betamax deck is almost around the bend as far as clean video playback goes right now though.
