Have you tried importing it into iDVD as it is? Typically, you don't compress
the video
until you are finished working with it in iDVD. Otherwise, the video gets
compressed
twice, which will cause a huge loss of quality.

Are you trying to transport the video from one computer to another? If so, then
either:

1) put it on a dual layer DVD (if you can).
2) cut it into two pieces (or cut out some unneeded footage) using Movie Player
and then
put it onto two disks.
3) connect the computers together and transfer it via cable

There may be other options if none of these is your issue.
