I know there's a two-disc DVDR somewhere that's widescreen... BUT all the additional scenes are in full screen and lower quality. I don't know if they're just inserted taken from tape and inserted into a DVD rip, or if it was shown that way on some TV channel and recorded from it...
I haven't seen it, either, so I don't know if "full screen" in this case means open matte or Castrate-n-Scam.
