I had an issue with ripping some DVD's to my laptop before a trip I made (note: no distribution occurred (for the lawyers :))). I wanted to just use dd to do it, but dd would fail after a small amount of data was read. If I first played a little of the DVD with mplayer, then dd would work afterwards. It probably had something to do with mplayer whispering sweet nothings to the DVD player. Sean -- sean-freebsd@farley.org
