You can use programs like DVDFab HD Decrypter
to backup your DVD collection to a hard drive.
You don't really need to keep a huge library of DVD's. Many of the book exchanges you'll run across while cruising also have a DVD section. Take in DVD's you've bought and viewed and exchange them for ones you haven't seen. Most exchanges don't appreciate copies. It's not uncommon for a boat to put out a call offering to trade
movies and books
with other boats in the anchorage.
Another use for programs like the one above is to remove the region code from a movie
. The more you cruise
, the more likely you'll encounter boats from DVD regions other than your own. Since you only have 5 region changes on your computer DVD player before it locks up you don't want to change regions every time you exchange a movie or buy one in a foreign port.
