Hehe, thanks Clutchins!
The commentary was ripped from Laserdisc as a commentary-only track (no other audio), and can be merged into whichever audio mix you like. But that initial rip, how it came about, and if there were errors in the ripping process, or different versions for different LD pressings, I just don’t know. I think schorman did made the initial audio rip, but I’m not sure.
Thanks for replying, Catbus. That’s interesting nonetheless and hopefully somebody will be able to figure out where the error began someday. I can’t imagine there’s too many people who still have access to the laserdiscs now (although if ever there was a place where they might be, it’s here!)
