Well, let's put it this way.  It happens.  We don't know why, but it's
hardware and running PAL seems to be the cause.  It has something to do

I see it happen (I'm in the NTSC wilderness, and it only happens when I
use PAL) but someone with better hardware experience can probably help
you out. (Dave?)
