Sounds like you're taking the long way around the barn.
Won't Adobe import DVD video directly? I mean before converting to DIVX. Better to skip the 2 extra conversion steps and save the video quality you'll lose that way.
There's a boatload of converter tools out there, most of which aren't worth much. For simply editing out sections of a program, DVD authoring tools can do that, like TMPGEnc-Author, again after importing the DVD video directly.
