Help with Nero Express. please

[marcos77]

Hi, I recently purchased a Verbatim DVD+RW/R and it can with Nero Express burnign software. I'm having trouble backing up my dvd movies? I get messages like can not compile cd. I burned the image file to my hard drive and then I tried burning from the image file to the dvd-r media but didn't work? Do dvd's have copy protection like pc games do? And if they do how do I bypass it? For pc games I use clone cd with no problem for backing up but I can't seem to figure out how to back up my dvd movies?
