I've had two or three rented movies with cracks in them ! so using Isopropol alcohol etc wont work. These ones of course you can take back and ask for another one.
But there are some that are just a bit scratched or worn that seem to play in DVD players but not my DVD drive.
I have used Ripit4me which seems to rip them OK, but looses part of the damaged tracks etc.
regards
Digby
