I agree with the error log piece as well as I just made a coaster on my machine trying to burn CDs without any type error. I actually left my machine and came back and it looked like everything burnt OK, but the first 5 songs would play, but every other track did not. That was a weird one for me.
I then tried to burn by turning off the direct burn feature and this time it hung up on the 4th song and MC never recovered. I rebooted the machine and tried to burn again, but the same problem occurred again where it got stuck on the 4th song.
I then opened up Nero and then dragged and dropped the playlist directly in and everything burned perfectly.
Not sure what is going on there as I may have to check some of the logs to see why it was failing in the first place, but I wanted to throw that out in case any one else is seeng something similar. Also tried switching direct burn back on again and same hang scenario.
