John, I have been trying to do the same for a few weeks with a DVD. There are many programs that wil let you read and then edit many DVDs (apart from mine) but the easiest I found was Roxio Easy CD and DVD, which allows you to capture the desired piece and then do what you will
I have also downloaded many other programs to do the same job with the DVD that I have, but still no joy on that score. If I can help, feel free to PM me.
