I think this version is currently the best all around quality version you can get although it isn’t complete. I hadn’t noticed until after it was released, but the “Smallville Flash” part of the drinking scene is missing. It’s present in the BLAX version and the YTV version, but not the ABC or 2 disc PAL version. It’s probably worth going though all versions just to see if there are any other bits exclusive to the different captures.
That is weird, because I used to have what I assumed to be an ABC-sourced bootleg (commercials cut out, “EDITED FOR TELEVISION” superimposed right after the opening credits, and I think there was a network announcement over the end credits) I got from a tape trade back in the early 2000s (along with the hard-subbed Danish TV broadcast of II and a VHS dub of the Japanese laserdisc of IV). And it definitely had the “Smallville Flash” scene in it, I vividly remember that.
(FYI, it came from REDACTED, a Washington, D.C.-based tape trader I got in touch with via the old Superman Cinema board, who I just discovered was later profiled in a Washington Post story on movie piracy. I have not contacted him since I got the VHS tapes all those years ago. I have no idea if it was taped in D.C. or elsewhere, since it had no ads. I also have no idea which airing it was. I got rid of the tape ages ago, though I MAY have sent a copy to a friend.)
