I am looking into buying a DVD Duplicator. Does anyone recommend any particular brand? Should I get one that has a hard drive. I am mainly looking to do 1 to 1 copying for the occasional copying dvds out of my dvd changer without having to go to a computer. I would like to copy protected dvds as well, but it looks as though that is not possible without decrypting them in a computer first. Any suggestions would be helpful. Thanks.
