Playing DVD movies without the disc
I found a great piece of software that allows you to play DVD movies from you hard drive on multiple virtual CD/DVD drives. It's called Alcohol 120% . The idea is that you backup your DVD movie to your hard drive as an image file, then you can take that image and mount it to the virtual DVD drive. Alcohol 120% even allows up to 26 virtual drives on one system. The down side is the a DVD movie takes up about 9GB as an image. This is great to use becuase you don't have to worry about the movie skipping or having to swap for a different movie. I also recommend DVD Decrypter to create your images since it has the ability to remove Macro vision and change the DVD's region.
