Splitting MPG's (Virtual Dub) Help Me Please!!!

[kurz]

I got an AVI file and I converted it to MPG file. When I went to burn it it says disk is not big enough. The file is 1.2 gig after converting it to MPG file.
Is there a way to split the file so I can burn it?
I was reading some of the messages and some said to use Virtual Dub,I don't know if I'm Dumb or what, but I can't figure out the program to split the file.

Once you convert the .avi to MPG you lose quality right? Can you just split the AVI directly then burn it? Thanks KROCK924**********COM
