you either want a program that is continuously & quickly updated to beat all new protections ( & accept that you'll get bugs & glitches as a consequence), or you want somthing that's very stable, gets lots of testing before it's released, & thus is out of date when new protections hit the market & won't rip your newer DVds

DVDfab is in the former category, name a DVD that it can't rip & they'll fix it I guess most competitor products are in the latter. e.g. DVD shrink is NEVER updated. HOw fast does anydvd update to defeat new protections ?
