Today I burned a couple DVDs with movies, and wanted to burn the third one, but after inserting it nothing happened (autoplay is on), so I clicked on the drive icon, and saw this: 
The disc is OK, other computer opens it. I tested some others DVD-R, DVD+R, CD-R, but I get same message. However, discs that contain files are recognised and everything is fine with them, just blank ones can't get opened.
What the..?
EDIT: restarted PC, now it looks fine. Just wondering, why this happened? Was that a DVD drive problem or Windows bug or what?
