Sorry for all the [rambling] self-followups, but I'm just writing
this because it seems no one else really knows the answers here.

The problem I'm now having is that 'gst-play' works correctly when
rendering to the entire video screen (i.e. when run manually), but
'gtk-play' (which is what is called from the "media player" icon)
is trying to redirect that video to a window on the screen, not
the whole thing and this is what is failing.

Anyone know how to figure out what gstreamer pipeline 'gtk-play'
is constructing?
