I have encountered a problem when I have tried to burn music to cd r. The drive will play music ok- so no problem there. However when I try to burn some tracks it will only record about 10 seconds. I will then get an error message saying that my cd is dirty or may be recording at wrong speed. Have tried other speeds without any success also tried downloading latest version of window media and closed all other applications that may have caused even a remote problem. Can anyone help or have any suggestions how to fix this problem?
