I have seen this problem and figured it out.  It has to do with the setting
as to whether the laptop screen or the external video port is the "primary"
vs "secondary" display.  My recollection is that we made both primary, but I
forget now.  If you have it wrong, then it will often work to play an MPEG
one time on the external port, but the second time you try it will be black.
Very frustrating and mysterious.
