Congratulations on joining the merchant marines! If you've never lived on a open-ocean boat, I recommend bringing ginger cookies. Traditional seasickness medicines put me into a 16-hour coma while ginger cookies cured my seasickness. I saw the Mythbusters test seasickness remedies and they preferred ginger, so I gave it a shot.
I work on fishing boats in Alaska and I use my MBP to play games and movies. I use mactheripper version 3. The link in the thread above is for the old version and I found that it would not burn some newer DVDs.

With mactheripper, you can decide to rip the whole DVD including special features or just rip the movie. It takes about 30 to 45 minutes to burn a DVD, so you have quite a task ahead of you. You'll be happy you did it on those long, lonely nights on the sea. Most boats I've been on have large movie collections, but there is no accounting for taste.
When do you leave?
P.S. You can watch the ripped DVDs on DVD Player, but download VLC too, just in case.
