My niche use-case: I have four young kids and a minivan with a DVD player for them. I've used it to rip DVDs that we own and burn just the main tracks to blank discs. That way the movie will automatically play, and play on a loop, when we insert the disc instead of going to a menu screen and requiring interaction with the remote control (which my wife and I can't do from the front seats, and my kids couldn't do in the early years). It also means that we handle the original DVDs much less often, so they don't wear out; I can always burn a new one when the DVD-Rs get scratched up.
