DVD Shrink

If youre looking for a great program with plenty of features and good development support to backup your DVD movies, try DVD Shrink.

Since most blank DVDs are single-layer and many DVD movies make use of two layers, youll need a program that can compress the data down to the 4GB allowed on a regular single-layer DVD disc. DVD Shrink does this easily and can create a disc image you can use with just about any burning software and a DVD burner. If youve got Nero installed, it will even burn directly to disc.

And you cant beat the price (free).
