The only hard part can be to get the content off the DVD and into some MPEG or other content.

If your video editor won't open such directly, use CladDVD XP to "rip" it off the DVD and open that with the video editor. I will not tell you where to find CladDVD XP but it can be found with http://www.google.com

I offer no support for this program, but note it as a method to get what you want done.

As to video editing, such usually come with the DVD recorder. Don't buy a video editor software since it will come with the DVD recorder. Wait and see if that's good enough.
