I can't see anything useful in the log even with debug at 99.. there's
also nothing useful in mplayer output. I may have a go at an strace
although I fear the strace log is going to huge since it happens maybe
every other movie or so.

I never saw this behaviour until I upgraded my old media box from an
old Athlon XP 32bit to a new dual core 64bit machine. I'm wondering if
it's a hardware or even network problem. Not quite sure where to look
at the moment.
