DVD Backup

For all your DVD backup needs, use either DVD Shrink or DVD Decrypter. IIRC, both can bypass the copy protection mechanisms. DVD Decrypter rips the DVD into individual files or into an ISO image. DVD Shrink can only do the former. However, it can decode/encode/compress the movie to fit the target media.

If the DVD is single-sided, you can simply rip the DVD without using any compression. To burn the VOB files and create a functional DVD, use ImgBurn. For ISO images, you can use CDBurnerXP, ImgBurn, BurnCDCC, or DVD Decrypter itself.
