How do you make a copy of a iMovie 08' DVD

[brainwave89]

I tried to make a copy of an iMovie 08 I created on a DVD using Roxio software but I get the following error message:
"Logical block address out of range" when I try to copy the iMovie to a DVD.

Is it possible just to make a copy of an iMovie 08? If so, what method would be recommended?

Thanks for looking.

Just use iDVD. It sounds like it could also be a media issue.
