george,
I am not sure where your file is, but the size of the file is um... interesting. The disk you have "copied" sounds like a dual density commercial DVD. I will not preach about copywrites and such, but I will say that If I am right about what you are trying to do... Good Luck! Most commercial DVD's have CSS encrypted protection. Even if you are successful in burning the DVD... it won't play because of the encryption.
There are some freeware programs out there that can be used to strip this protection, but you are still left with the problem of the 9+ GB size of the DVD. As far as I know, there are no mac compatible programs out there that will split this file into two (so that it could be burned on two DVD-R's.
The only solution is to use even more software to rip the individual audio and Video tracks off of the disk and then try to compress them down (losing much quality) into something that will fit on one DVD-R. You would have to do this manually with every file, and re-synch the audio and vidoe tracks before burning. This process can take several days to accomplish on a fast mac.
If I have guessed incorrectly what your intentions are, I Apologize--- it's just that those file sizes match exactly.
I have intentionally left any and all links to software mentioned above out of this post. I happen to subscribe to the Fair use Doctrine for Commercial DVD's I believe I should be able to make backups of DVD's I own... However the other use of this type of software would be piracy plain and simple. Hollywood does not agree with even the fair use argument.
There are several programs for doing the above available for the PC so... ??
