I've never heard of this before. I've tried 2 different burners. It started with a Samsung and thinking it was failing I bought an Asus DRW-24B1ST and it does the same thing. The discs are Verbatim DVD -R if that means anything. Haven't tried another brand yet.
They both read and play discs that have stuff on them already. Even reinstalled Windows 7 (needed it anyways), and it still happens.
I've been having other issues with this system and this is the latest. Starting to wonder if the MB itself is bad.
