As others have noted, TV output displayed using xVideo cannot be captured
in a screenshot. The usual workaround for this is to use a different video
mode (for example, xShm, or X Shared Memory) to take the screenshot.
I know (the hard way, alas) that if xVideo support is not available in the
X server, mythfrontend will use some other video mode (I'm guessing xShm,
but I don't actually know this). How to force this switch if xVideo *is*
present I do not know ... perhaps a more experienced MythTV user than I can
suggest the way.
Of course, if the problem you are having does not occur with this other
video mode, this method will not let us see it.
