And do the whole movie on one disc?"
You can burn a DVD onto a CD (called a mini-DVD), but the quality will be inferior, and you'll need two discs (This is similar to how VCD's were done.) Neroburn includes this option under CD formats, but again, I wouldn't recommend it.
I'd suggest getting a DVD burner instead. The prices are dropping all the time. Hell, you might as well go get the Sony 2-layer burner at this point, which had a gtreat starting price.
