As for personal burning, the only illegal art of that is downloading Smartripper, transfering them to another dvd would be the same as making a playlist.

This is another constradictory issue. You're alowed to make backup of your discs, and consequently trailers so long as it's for personal viewing. Thus it can be argued that using SmartRipper isn't illegal. How could you back it up, as the law permits, if it's protected?
