I found a solution.
My problem was that I had converted my Vob files (from my camcorder) into mpeg files using power director.
Full Story
Power director kept crashing when I tried to edit the Vob file. I had read that a vob file was just like a mpg file. I had also read that simply changing the extention from .vob into .mpg would do the conversion. THIS IS FALSE.
I discovered a free product from badgerIT that converts the files from vob to mpg (I think its called VobtoMpg).
I converted 2 of my discs using this free product and then discovered that powerdirector offered this option by saving the file as a mpeg2.
My file played fine on power director but when I put it on DVD. The same scenes would display a green/blue fuzz (small squares) then it would freeze for about 10 seconds.
I decided to use badgerIT product again re edit the scenes again and this fixed the problem.
Hope this helps some1
