This doesn't mean much to me, but it may give some clues to someone else:

Taken from logwatch.  The hdc errors are when I have a dvd recorded with a 
weak signal.  They often will play on my standalone recorder, but not on this 
box.  I ignore them, but the sdx errors are more likely to be connected with 
the runaway problem.
