Windows Media Problem

Sorry for having to come back again with the same software giving problems. I recorded audio files from the internet. When I try to burn the files in WMP I receive the following error message.

Windows Media Player cannot burn the files to the CD. Verify that the disc is clean and not damaged. If necessary, select a slower recording speed or try a different brand of blank discs.


I have been burning this type file daily, but now this problem started. Any ideas of what I am doing wrong?????? I have gone through 10 CDs so far and none of the recorded nor could they be used again. Thank you for your patience with my problems but I don't know how to resolve them


Thank you,

Wadda
