It sounds like a fan/bootleg but that's kinda strange because it was shown at least 3 years before the movie addition was available on VHS and didn't have any of the other extras from it. (but could have been edited with a japanese version I suppose)
I tore my basement apart looking for the itinerary from that show but couldn't find it.
I shot an e-mail off to the Otakon people, but they are just getting finished with their last convention and are gearing up for the next one, so I don't expect an answer.
One thing of Note: The sub WAS a bit different from my laserdisc, which gives more credence to the fansub theory.
If anyone comes across this version Please post a thread.
Thanks, everyone.
