also i have the '82 laserdisc, this has different pan and scan than the later ones, including a squished scene where luke sees the tusken thru his binoculars instead of it being cropped. i read on the davisdvd star wars video timeline that this version was only shown on HBO in the early '80s, and never released on video.
and what was different about the '80 stereo mix of empire?
thanks karyudo, can anyone answer my other questions above
