CloneDVD by far! This program is so esy to use and is way more powerful than XCopy or Xexpress. I have full guides at my site for this program and more like DVD Shrink which is also a excellent program. PS, DVD Shrink is free!
I agree with Koola...DVD shrink is a fantastic programm and is very easy to use and if you use the latest version (3) or something like that it will shrink and do everything automatically...then all you have to do is burn your movie...i myself do not have any brought software for making bacup's and i personally swear by DVD Shrink it is the only programm i have used since i learned how to make backup's through this very forum.....i have had outstanding results both with the graphics and sound quality....and like Koola says it is free.
