yeah, if they have a video projector, you can probably just hook up a deck of your choosing to it. heck, most of the smaller festivals at sundance project dvds off of a 30 dollar walmart brand dvd projector.
I’ve done this numerous times…i agree, make sure to talk to the theater, check the projector..out put, and then WATCH THE OUTPUT MEDIA, if its a dvd, watch it on the dvd player that you are going to project it with, and if its a tape, watch it before you project on a tv. that way you wont have a surprise.
bring a backup, in fact, bring a VHS backup…it’ll save your arse. I flew with a friend out to tromadance 2004 in park city, and his dvd faltered….and yeah,we had to finish with a vhs tape, but at least we could screen!
