There are 2 different in-MythTV approaches to getting screen shots.  The 
SCREENSHOT key binding and the ScreenShot jump point.  They have 
different behaviors.

Note, also, that the SCREENSHOT key binding--which will always work, 
regardless of video renderer--will cause a UI lock up on 0.22+ or so.  
You seem to be using the jump point, which only works with some 
renderers, but would actually show anything on screen (captions, menu, 
OSD, ...).
