This looks like a bad burn. Bad burns are caused by wrong settings, wrong format or bad disc. Try to burn another disc and carefully choose the target destination of the DVD. If you want a DVD video, select the DVD Video category and so on. If you create a data DVD and want to view it in a DVD Player, you will have no success at all since the DVD Player might not recognize the DVD you have just created if it's not in the right format. Ashampoo Burning Studio might be a good alternative.
