Trying to learn CloneDVD. Sticky's instructions say to change booktype to dvd. I dl'd Nero CD-DVDSpeed, but it locks up my computer. Dl'd Imgburn, tried to change booktype, and it just keeps failing. Have a Compaq Presario laptop, LG HL-DT-ST DVD+RW GCA 4040N burner. Any help much appreciated. I'm not very computer literate, so please keep it simple.
