I have some suggestions for anyone backing up their movies. I have been backing stuff up for a while but still consider myself a newbie. A few suggestions would be, stop trying to cut corners or find some fast way of doing things. Run as few programs as possible. avoid opening new progs when burning DVDs. I use an external NEC burner via usb 2. I decrypt to external drive and shrink to local drive on my laptop. I stopped using NERO due to too many errors with the external drive. I now burn with RecordNow DX and it works flawlessly. I also use Princo white top 4x dvd-r's and have had great success with them too. I decrypt the movie with decrypter, shrink it with dvd shrink and then burn it afterward. Patience is the key. hope this helps.
