How long is it?  Judging by the file size, I'd guess 3-4 hours?

A normal movie at 6000 kbps and typical audio, will fit on a 4GB DVD, so 
I'd take a punt and use ffmpeg (or mencoder) to convert it to 3000 kbps 
and see how you go. If it compresses well, it might fit. Maybe juggle 
the quality settings too, until you get it to where it fits and is 
sufficient quality.
