The script uses MacTheRipper 2.66. It might require a bit of setup (ie, rip a DVD to your ~/Ripped VIDEO_TS folders/ path or something like that), but otherwise should work fine as long as GUI scripting is enabled. Simply select it in System Preferences as the course of action to be followed by the system when a DVD is inserted, and you're good to go.
In addition to this, I have a script that is called from my nightly cron that controls the CLI version of Handbrake, and converts the VIDEO_TS folders to H264, moves the video to the appropriate external hard drive, and then moves the original VIDEO_TS folder to another path (not deleted -- in case of something weird -- the other day I had a DVD with a "Behind the Scenes" feature longer than the actual film!).
Again, there might be a way to make this more efficient ... but I'm a beginner.
