Did you check your logfiles in /var/log?
Mostly if linux notice errors it will write to a logfile, like /var/logs/messages or /var/log/system.
Just start a burning a session and see if the date-time stamp on a file changes and look in that file at the bottem. See if you find something usefull or post on the forum.
Thinking of this i vote for a eventviewer alike application which shows the most important log files
