Well, that's another thing...

There's both an in-playback screenshot capability that uses the 
SCREENSHOT *keybinding* and a GUI screenshot capability which uses the 
ScreenShot (yes, capitalized differently) *jumppoint*.  The in-playback 
screenshot is in libs/libmythtv/tv_play.cpp in TV::ActiveHandleAction() 
around line 4160.  The GUI screenshot is in the 
MythMainWindow::screenShot() functions.

The GUI screenshot uses ScreenShotPath, but the in-playback screenshot 

    QString outFile =

TTBOMK, the GUI screenshot jumppoint still only works in TV playback 
with certain renderers and, when it works, includes the OSD.  The 
in-playback screenshot keybinding works with all renderers and does not 
include the OSD (or captions or ...).

See http://svn.mythtv.org/trac/changeset/16532 for more on the GUI 
screenshot jumppoint and http://svn.mythtv.org/trac/changeset/12908 for 
the in-playback screenshot keybinding stuff.

Yeah, I know.  Consistency...  If no one else gets to it, I may actually 
find some time to work on improving the consistency (including allowing 
the jumppoint to fall-back to using the in-playback screenshot 
capability when we're using a renderer that won't work with the 
jumppoint capability), but it will be a while.  It's been on my TODO 
since the GUI screenshot went in, but it's not high on my list (at all).

Haven't tried it on trunk, so I haven't seen that.  Is that the GUI 
screenshot or the in-playback "video" screenshot or some weird issue 
resulting from having both the keybinding and the jumppoint mapped to 
the same key?
