DVD to PC

Not sure how to finalize the DVD, but either way it is a few years old and we picked it up for cheap and it didn't come with any software so a friend mentioned that could be the problem. We have an HD tv now and a newer laptop with a widescreen HD format so it's time for an upgrade anyway to get better quality. Old camera also makes an annoying buzzing sound when zooming in during a hunt, doesn't bother the deer but you hear it on the playback. Also not the greatest camera in low light, so like I said just time for an upgrade.
