Tried to burn a CD of mp3 songs using MM3A6:
1. Rec'd MM3 error message 199680
2. Chose reburn, inserted fresh CD
3. CD writer powered up to full speed & stayed there, with no progress on progress bar. Right-clicked on progress bar & chose terminate. Closed MM3.
4. Task Manager revealed MM3 still was running in the background
5. Couldn't eject CD
6. Shut down computer & chose terminate when computer said it couldn't close MM3.
7. Rebooted, gave MM3 another chance, receiving same error again.
8. Gave up after 3 wasted CDs

and burned the CD using ITunes w/o problem - same drive. Before doing so, I again rebooted as MM3 again continued to run in the background after program was closed.
Using Sony CD-RW CRX220E1, 52/24/52
2.4 Ghz P4, XP Pro 1 GB Ram
I was in the artist node when I started, highlighted the tracks - all from 1 album - and then chose " Burn CD/DVD" from the Tools menu.
Thanks, Danny
