Nice - [edit] except it's wrong to pirate software and it's against forum policy to advocate it.
I've found
MacTheRipper to be very good, and it allows you to rip the feature presentation only should you desire, which reduces the need for compression. I've never, not once, had a problem ripping with it, and never need to open DVD Player first. Maybe I've just been lucky.
Also, I've been happy with
DVDRemaster as a compression tool.
These are just other options - the steps mentioned above are the right route to take.
And I agree - Toast is a necessary final step!
