Wrong forum, but... Depending on the filetype, use DVD Decrypter (http://www.mrbass.org/dvdrip/), and burn in ISO mode. A more updated (but IMO, worse) image burning tool is ImgBurn (http://www.imgburn.com/index.php?act=download). Have fun!
[bold]Not Correct[/bold] If you want to back up your DVD you can use NeroRecode with AnyDVD running in the background, AnyDVD will break any copyprotection and it's available free for a 21 day trial from slysoft site.
not back it up i already know how to burn the disc but how do i get the image of a disc onto a burn blank disc
Your question is a bit ambiguous, do you mean you would like to copy the front cover of the disc to a blank disc so to make it look like the original, if so you will need either lightscribe capabilities or an inkjet printer with the capabilities to print to the "ink jet printable" disk, such as Epson or Canon
