I assume you are burning a CD rather than ripping. Could you post your system info (from MC's help menu)? Is the CD really empty, or is it partially written so it's unusable afterwards? Have you tried reading the burned CD after restarting MC (or rebooting)?
Thanks!

I tried rebooting too; it didn't make any difference...
Update: I tried again after using "test mode" first, and something even weirder is happening--it appears that attempting to copy mp3s to disc is generating a playlist (and I think its supposed to do this), but the mp3's themselves aren't anywhere to be found on the disc. It's empty except for the playlist. Through various attempts, I now have a set of 6 CD coasters, if anyone is interested in purchasing them....
