Hello. I have a problem again: I have some CDs of my friend, but they cannot be played on the PC. At first I thought the problem was that the CDs are scratched. Many of my friend's CDs are scratched so that some songs crack and are interrupted. But there are 3 unplayable CDs which are not scratched so much in comparison to others which can be played. Then I realized that there is the inscription VCL on those 3 CDs. Well, what is this, why can the PC not play this and can I do anything to solve the problem?
I know this is a technical problem, but as it is a matter of music CDs I guessed that somebody here might ba able to help me.

Thank you so much!

Bye
