I use Nero .... there's this very small programe called AnyDVD that tricks your burner by removing the copy-right and region code .... lets you copy... your copy is copy-right and region free to play on any dvd player...
DVD Shrink i find is the best (and it's free) in combination with ANY DVD aND dvd43 you can burn most dvds... but of course you are only trying to backup your original dvds to keep them in perfect nick right? burning dvds that you borrow is illigal and i'm sure justcommodores would not condone this being promoted on the forums. (i'll delete this post if it is out of line)
