quality being grainy? Hi, I am trying to burn a video to a DVD, but every time I burn it and watch it, the picture comes out on my TV a very grainy and distorted. I need to know how I can fix this. Is there some type of software that can help increase video quality? I am using windows Movie Maker to burn it, is there something better I can use? By the way, the software needs to be free!!! And I would like the software to be a full download, not just a free trial with some annoying watermark in the middle of the screen that doesn't go away until you purchase the product. So I guess what I need is something that can enlarge video size. Thanks!!!
