If you have
Nero Recode then you would probably also have Nero Vision. Using Nero Vision, you can import DVD titles into your Own DVD creation. Once the title is imported, you can select the individual parts that you want to keep and trash the rest. I've done this with episodes of SouthPark (just playing around mostly) but I haven't ever finished the burn process. I will attempt to do this and see what happens, then I'll try to get back to you.
