I'd like to kindly offer a suggestion to the authors of DVDFab. Since the start of version 5, DVDFab has had a great many improvements in features and new product lines (VideoFab, Blu-Ray, etc.). However, the general use of the program has gotten less and less stable. This goes for both the full and beta versions. Also, people that wouldn't normally install a beta version are often doing so because they need a fix for copy protection on newer titles. This problem is not new and is faced by many many software projects both past and present.
I suggest that DVDFab be separated into stable and non-stable branches. DVDFab almost has this already with the full and beta versions but is missing a key feature. Both stable and non-stable branches should be able to be installed on the same machine at the same time. This allows people to test the non-stable branch and still use the stable branch when something isn't working.
This arrangement will take some pressure off of the authors to continually come out with newer versions quickly. You only need to release a new non-stable version when you want feedback from user testing. When new copy protection or other important fixes are needed then you would need to make the change to both branches.
It sounds like a lot of extra work but it actually makes life much easier. You can take as long as you need to perfect a new feature because any pressing updates can be made in the stable branch. When your happy that the new features work and all existing features still work then (and only then) promote the non-stable version to stable.
I hope you find my suggestion useful.
