Any DVD and DVD Region + CSS Free are running in the background and can serve a lot of programs that rip, shrink and burn but do not decrypt. DVD Fab Express and Gold does decript so does not need any of the first mentioned applications. On the other hand DVD Decripter is a free application to rip even recent releases to HD and then you can use DVD Shrink - another free application - to shrink and also to burn the results. But the folder created by DVD Decripter is not always readable by DVD Shrink. This "combo" is free so you can not complain anyway.
AnyDVD and Clone DVD2 come from the same developer and are a "combo" and can be considered as a competition to mDVD Fab. On this forum it is not polite to praise products other tha Fab. However there are people here who curse Fab and praise Fab and if you visit the AnyDVD forum you will see complaints about AnyDVD there as well.
All this depends on your PC system. If you have a stable one you should be able to run any of them otherways you have to try which suits you.
