Just yesterday I picked up the Sony DRU-510A DVD+/-R(W) drive as a birthday present.
It is definitely a nice drive to have in order to back up all my personal files such as emulators/games/mp3s onto one or two DVDs instead of nine or ten CDs. The greatest thing, however, has got to be how having a DVD burner allows me to mess around with all of my DVDs and compile discs for special purposes. (Like being able to correct the absurdly low volume levels of the Trey Parker and Matt Stone intros to the South Park episodes). However, the neatest thing I've done has to be with my Bond movies.
I was watching Goldeneye the other day and thought about how the intros/opening titles are some of the coolest parts about Bond movies and how sweet it would be to have a Demo disc of all 20 intros. When I installed my burner yesterday, that was one of the first things I did. I went and spliced together all 20 intros to the Bond movies onto one DVD. It's a pretty sweet little disc to pop-in when I just want to watch the intro/title sequences of certain movies.
