You used to be able to buy a little box thingy that mounted on the video camer and projector for doing just as vagt6 suggested. Had an opaic screen built in that the film projected against and the video camera then filmed. A search on e-Bay might find something.
BTW I still shoot our family movies in 8mm (not Super 8, but the earlier Regular, or double-run 8mmm, and yes, you can still get the film although not cheap, and the cameras and projectors are available for peanuts on eBay).
Much prefer it to video - has a nice grainey quality, and the format forces you to be sparing with 25ft reels lasting only 4 min. (Ever sat through someone's 2 hour wedding video - I thing you will realize the advantages of 8mm). Also 8mm film is forever - never gets lost in a disc crash, or gets corrupted so will not play.
The camera gear (60's vintage all-metal and leather construction) is a pleasure to use, Bolex brand swiss made stuff is the best. And setting up the projector, screen etc has a real ritual feel to it. I also have 8mm film my parents shot when I was a kid so its nice to have the continuity across the generations.
Didn't mean to take the thread off-course, but 8mm gets my vote (has many of the qualities of owning an old British car now that I think of it).
