I always use DVD Shrink to backup my movies. I use TDK media and have also noticed the problem on Ritek and Samsung media. Sometimes, if I hold a burned DVD up to the light and hold it at a certain angle, I can see 1 or 2 small, dark spots on the DVD. It's hard to describe. It looks almost like a very small spot on the dvd didn't burn. It looks as if the spot is the same color as the DVD was before I burned it. The movie plays fine and the DVD passes any integrity tests I throw at it. Is this normal? I can't notice the spots unless I hold it up to the light and look for it hard but it is there. Anybody else experience this?
