I have a copy of "Lethal Weapon 4" that was in a bundle that was received free by mail with the purchase of a DVD player. This is going back a few years but I have noticed there is a "Lethal Weapon 4 Premiere Collection". When I do a price search on DVDPricesearch.com, they only list the "Premiere Collection". My question is, what is the difference between the 2 (if any). The copy I have states on the back where the UPC should be, "Not for sale 16075 Promo" and the disc has numbers 16075.1.A. The cover on my copy does not say "Premiere Collection" across the top over a gold band just "The Gang's All Here" Thanks.
