i watch and delete, but if something's just too great to discard, i burn them onto DVD-Rs, cdr's take too much space, and they burn themselves to hell easily. i use sony dru with its supplied software, and the recorder itself verifies every round of the burning so i almost never get failed stuff.
which is why i use generic stuff...gah they're so cheap, there's not point in worrying about them going wrong either way, most of the stuff i end up liking get licensed, so i have to throw that crap out to get the DVDs...with boxes and everything,
eh...i'm not very helpful, so good luck with whatever brand you end up using.
