Update. I was just back in the lab, I tried playing the video again -
and was distracted while talking to a colleague. About 45 seconds later
faint images appeared on the screen. The movie was just "fading in". I
was mislead because it plays *so* slowly - about 1 frame per second is
my guess.
Does anyone know if/how this player can use multithreaded decoding?
