That's right, Mactheripper is simply for creating backups of dvd's you own. It is a fine program though all the same. I could give you a list of others also.

As for burning dvd's on a mac, the dvd's should be burnt in UDF format which is the official dvd video format. Those burnt as data disks may not play on many players.

I'm only aware of 3 video burner softwares for mac osx (excluding the system's finder, disk copy, disk utility & iTunes.) One is free but is crappy & I refuse to recommend it. The other is made by apple. But the very best, & has always been the very best burner program for Mac, is called Roxio Toast. The most recent version is Toast Titanium 7. It is very good for all burning needs. Get it!
