Making DVDs

At adolph's instruction i tried to image one of the photoshop training videos. It won't work. Disk Utility in os x won't let me do it cause i don't have 'permission' and disk copy in os 9 won't do it cause it's too big (greater than 2 gigs).

Any suggestions? (besides copying it to a vhs tape - which is what i'll prolly end up doing if no one comes up with anything.)
