The blue screen is xvideo not working properly.   I get this all the
time in certain nvidia configurations but only after I try to play 1080i
video, which I dobut you are doing.

xvideo works by slapping up a rectangle of a certain magic colour (often
a bright blue).  The xvideo hardware knows it should overlay on top of
this colour.  It's how you fake your windowing system overlay support
into xvideo which is deep in the card hardware.
