Video Camera help


I got a new camera so my video quality would be less… bad. I just did some recording and I don’t know how to transfer them to the computer. The camera uses DVD and I’ve already finalized it. When I try to put it on the computer, all my clips come together as one, and I can only watch them when the disk is in the computer.

1.) How do I get them into the computer so that they’re there to stay?
2.) How do I seperate the clips?

Sorry that it sounded so confusing. It was hard to explain.
