This happens almost every time I make a burn. When viewing my newly burned dvd, about half way thru the movie the picture starts to freeze, jump, etc. I think I`v heard this called pixelate. I see the same type thing happen to my direct tv picture during a hard rain. The only time I get a perfect copy is when I`m copying a brand new movie. I use a sony burner dl. 1click and dvd43. I use verbateum blank dual layers. So far I have wasted about 12-15 expensive blank dvd dl. Any ideas???
