I didn't realize he was asking about "movies" ie AVI/Quicktime etc movies. He said "video" which could mean anything and since he has 2 FT monitors I assumed he'd want dual dvi outs.
But if you just want to play a movie on 2 screens I think any card will do that. Just use video mirroring (this is what Nvidia calls it, not sure about Ati) on the 2nd monitor then maximize the MP window on the 1st. I dunno if this works for 2 monitors but I know it works on my GF FX with 1 monitor and 1 TV set.
Of course that will play the same movie on both screens. If you want to "stretch" the movie across the screens, meaning play the left half of the movie on monitor 1 and the right half on monitor 2... well then I guess you got to go with plan B, above. That's a pretty stupid thing to want to do though, if you ask me.
