help how can i back up my own protected data dvd for safty , si there any progrms out there ?

I use one with the same name as the title of this thread. For a good list of what's around see both: http://www.videohelp.com/ (it's a big site with a large forum so you need to look around) & also http://forum.dvd-guides.com/

thank u 4 ur help lord but i didn't make my self clear the dvd i want 2 back up is a protected dvd rom

And that's exactly what my answer was refering to. For mac dvdbackup will decipher all security on the disk to allow you to make a copy to your HDD. I then use another utility to reduce the size to dvd5 format size (4.37 GB.) And for windows there's equivalent apps.

http://www.videohelp.com/tools & the other dvd link I gave you. You just need to look thru.

thank you. new user didn't quite know how to reply. thanks for the info. hope i can make it work

Very simple if you have the right apps. At those sights they actually give a list of exactly what you need to do & what steps to take & which apps to use. I don't remember exactly what page it is so you'd need to search for it.
