Paul would like to rip DVDs and then put it on a 128GB thumbdrive so that his kids don't trash his DVDs. Leo says that's a great idea and you can use both Handbrake and VLC Media Client to do it. But how does he convert a DVD that's PAL? Leo says that the DVD is probably region coded to prevent you from watching a DVD from another country here in the US. The first time you play the DVD, it sets the Region code. But there are DVD players that don't do it. There's also a few back doors that respond to a certain number of remote button presses to unlock them. Google your DVD player model number and "remove region code" and you'll get the procedure.
But then you have a frame rate issue, since PAL is 25 fps. You can reconvert them by ripping it.
