None taken :)  I certainly don't have all the answers.

I suppose my point is that the world is bigger than KDE and Gnome.  If I can
support GStreamer and others by a simple conversion, then perhaps I should.  I
cannot write individual conversion for every application and framework out
there.

This doesn't mean I won't look at it, you've piqued my interest.

Sounds interesting.  I'll look into it.

Nope.  The sample comes from a Hauppauge PVR-250 which is primarily an MPEG
compression engine (iTVC15 based).  As I mentioned upstream, this really looks
like an intermediate step between YUV and MPEG.  MPEG does motion prediction
on the Y plane in 16x16 blocks.

This format was also returned by the Windows driver when an untagged pin in
GraphEdit was connected up.  Hauppauge has recently released a beta ".ax" file
to deal with this on the Windows side.
