I wanted an app to make ripping a decent-sized (900+) DVD collection to ISO disc images, and it'd be hard for an app to make the process any smoother than MDRP.

With the correct settings, I stick the disc in, it automatically tries to grab the movie title, starts the rip, then when it finishes it dings and ejects the disc. I can just sit near the computer and swap discs when one pops out--hard to get any simpler than that.

It also seems to do well on imperfect discs; MDRP didn't complain while ripping a sketchy disc that RipIt spit out and refused to rip (the rip didn't have any obvious playback problems). When I gave it a disc I knew was bad--no DVD player I've tried it on can play it--it went ahead and completed the rip (I could hear the drive slow down when it hit the bad spot) then warned me that the disc had 18% bad sectors, and the rip was probably bad. Indeed, it choked on the same spot a physical player would, but it was otherwise playable.

That's exactly the behavior I want in a situation like that--do the best you can, keep the result, then warn the user.

Only once has it failed to rip a DVD, and that was a VERY early disc (the first anime DVD ever in the US), which it didn't like the format of.

It's also apparently stable--it hasn't crashed so far in about a hundred discs, although twice it hiccuped, saying it could't create the image, while immediately re-trying worked fine.

My ONLY complaint, apart from those unexplained hiccups, is that the preference window is a weird custom deal, not MacOS standard controls. Which is a pretty minor complaint, given that it's only got a few options.

Also, the developer said it was ok to use the same license on a couple of home computers ("within reason") simultaneously, which is very generous for those of us who'd like to speed things up by doubling up rips. It's unsupported, but apparently you can even rip two discs simultaneously by launching two copies.

Overall, fantastic value for the money, and altogether worth it.
