Windows Media Player 10
 

All the songs in my burn list first are "converted." Then the first song starts to burn, but shortly thereafter a "closing disc" message appears after each title in the burn list. A small window appears telling me that WMP cannot burn the files to a CD. I'm using Memorex CD-R discs, and have used them before successfully.
Windows XP Professional
Version 2002
Service Pack 3
Any help would be greatly appreciated!
