Sorry I take so long to respond. I hope the other posts have helped. There are three issues to be solved: First is getting a digital copy of a movie. DVDs are encrypted, and though software is available to break the encryption, it is illegal. You can get around this by taking the video output of a regular DVD player into a PC video capture card. the quality will be lower.
The second problem is capacity. DVDs have a 9 gig capacity -- about 15 times that of a CD. You can get an entire movie onto a CD, but only at a much lower quality. If you are talking about clips of a few minutes or so there is no problem.
The third problem is format. If you only want to play the result on a computer this is not a major problem. If you want to play the CDs on a DVD player, you need to go to the help web site and study the options.
