IMGBurn is better IMO, and it's free. You can even use this guide to help you... http://forums.afterdawn.com/thread_view.cfm/383878
You can also use Shrink (a free program) to create an ISO File. The advantage to that is it will shrink the file to the size you need for a single layer disc at the same time it encodes the file. Then I use Imgburn (also a free program to burn). If you are doing some of the newer movies you will need a decrypter program like AnyDVD. It costs about $40, but is worth every cent. In my opinion it is the best. It has free lifetime updates. It updates everytime some new encryption comes out.
You don't know he's talking about making ISO files of dvds now, do you? ISOs have lots of other uses too.
