Divx Cut Shorter after burning, but not smaller in size

[Dark-Scorpion]

I have a 675 MB Divx, which I tried to burn to a cd a couple of times, but everytime I try this, it burns all 675 MB's on the cd, but the movie is only 40 mins long or so instead of 2 hours. It basically cuts alot of minutes of the divx. I can't find anything what could've caused this problem anywhere, since the divx works fine when I play it on my harddisk. All help is greatly appreciated!

Thanks.

Are you just burning the divx as a standard datacd?

Yeah, and I even tried 2 different burning programs for it, Nero and EZ CD Creator).
