Ok, I've gotten more of those messages when the box didn't freeze so
i'm thinking they're not related.  Any chance this could be happening
when the box gets too hot?  It only seems to happen when we're watch a
recording or live tv.  Often this means the box is recording a new
show, commercial flagging one that has just completed and also playing
back whatever we're watching.  The CPU does run a little hot (55c),
but still significantly lower than the max (70c).
