Julian- assuming you're the same person on the HQ boards that was looking for the promo tape from Sony for the 99 DVD, I'm flying home to CO this weekend and will grab my stash of rarities and dub a few DVDs for you. I should have the following:

1) Ghostbusters Spooktacular - Various Videos from the USF Attraction including excerpts from gift shop video

2) RPJ Music Video (with the original John Candy/Jeffrey Tambor/etc. dialogue - not the MTV2 version). Consequently, did you know that the cameos were the reason they couldn't clear the rights on the music video for the proper release? That's why it's harder to come by.

3) 1999 Sony Publicity demo reel for the original 99 DVD release

4) ALL content from the Criterion CAV Laserdisc, second generation (sadly) dubbed onto VHS from the original disc

There might be a couple other tapes there collecting dust that I've completely forgotten about, I'll keep you posted (and post over on the HQ boards too, in case you're frequenting there as well).
