Know which one showed up first? And, maybe have the actual error messages?
The 'audio behind' message should have a couple of numbers after it, and the
first few times that shows up would be interesting to see..

I've not had happen, but I don't think it was due to load.. The lock up
probably happened because the audio and video were so far out of sync that
the player didn't know what to do to get them back in sync. Not sure why the
audio recording started lagging, though..

480x480 at quality 170.. Not enough difference on my tv + viewing distance to
be worth the extra space for higher res/higher quality, though that may
change soonish.. I've not noticed any problems with higher resolutions,

The numbers for my athlon 1800+ are much lower, like half those -- are you
running a debug build, or is the celery really that much slower?
