DVD Backup Issue..

I'm trying to backup an old dvd that has tons of scratches, so i wanna back it up before it's too late.

Anyways, i was able to extract all the files and everything, but the file sizes turn out to total 5.6 GB.

Is there a way to burn that on a 4.7 GB DVD-R?

Unfortunately my only suggestion is Roxio Popcorn but thats money unless you get it from a P2P and that can be hard.

I'm waiting for Macman to get back to me about a program beside Popcorn.

no, use dvd2onex, its the best, then use popcorn to burn if you like, it wont need compressing within opopcorn and the result will be better quality.

But once again dvd2onex only does 30 mins of the movie in the trial version
