First thing I would do is install DVD Decrypter and DVD Shrink on any system trying to do these.
Then, for ripping DVD’s, RipIt4Me and DVDFab Decrypter are really good. I prefer the RipIt4Me app with their installer, but DVDFab will do the trick.
Once you get the things ripped, DVD Shrink is great for tweaking the setup and creating a VIDEO_TS folder that you can burn with ImgBurn or some other app capable of doing DVD Video projects, like Nero.
I like to use Ulead DVD MovieFactory 5 to combine content, make chapters, menus and such. It is not free like all the rest of the stuff I listed above, but for $50 it does a fantastic job.
