bollocks - completely missed what you were saying about dvd - My advice would be import your movies into after effects/final cut pro and then output the finished movies to dvd. I'm pretty sure you can bring flash into either of those (but don't quote me)
If it looks fine on your tv it'll look fine on plasma.
I'll check with my mate Mick as he's done loads of this type of thing.
