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?
Actually I am one of those people who use a can of comressed air before I burn! I always have a can gandy and I make sure the disk is VERY clean before I start burning. Well, I am beginning to think ti may be my DVd burner. I am going to buy another one tonight and try it out. If I have the same problem, I will take it back. Take it easy.
This has happened to me when I haven't burned the dvd at the correct speed. I had Ri-Disc Ritek G04s which are 4 speed and tried doing them at 8 speed in my hacked pioneer 107D and it gave that effect, the same with other cheaper 4 speed media. But when I tried the new 4 speed Datawrite Yellow V2 Ritek G05 disk at 8 speed there are no marks/bloches whatsoever. And before I burned I always make sure the disk is clean so thats what I put it down to.............but I could be wrong!!
I am curious, did your new burner fix this problem? I have had the same problem with the TDK and Memorex media I have burned lately. There are one or two very tiny spots that are dark and appear to be areas not burned to. However, the media plays fine so I am at a loss for what causes these spots. Do you see these spots with your new burner?
