Is anyone keeping up with this? ;)
I can say with confidence that the HBO recording and the 1983 Laserdisc are from the same time compressed master. Even the film scratches are the same.
The whole custom 16mm transfer made for HBO story is full of holes now. ;)
Where the heck the second betamax copy I have was recorded from and when, I have no clue. Unfortunately, it has hopeless tracking issues that don't clear up until several minutes into the movie. I think the '83 Laserdisc would be a much better option than using this to patch or replace the HBO. You also won't have to speed the video up.
My second pass off the "new" Beta got me as good a capture of the HBO as we're probably going to get. Spots where I knew there were dropouts previously didn't have them this time around.
I will try to post screenshots later this week.
