Public bug reported:

I installed XBMC from the wsnipex PPA
(https://launchpad.net/~wsnipex/+archive/xbmc-xvba) because it has XVBA
support, which I need for playing 1080p movies (my CPU is a AMD E-350
and can't handle much). Unfortunately, when compiz is running XVBA fails
to set up a decoder session and I get a blank screen. The following
message shows up in the xbmc log file:

    ERROR: XVBA::CreateSession - failed to create decoder session, line
633

When I start XBMC by first replacing compiz with metacity everything
works fine.

Their are numerous reports on askubuntu, ubuntuforums and the xbmc forum
which mention other playback problems related to XBMC (and other
applications in full screen) having problems when compiz is running:

http://askubuntu.com/questions/209460/xbmc-using-a-lot-of-cpu-when-fullscreen

On the XBMC wiki
(http://wiki.xbmc.org/index.php?title=XBMC_for_Linux_specific_FAQ#Compiz_is_not_compatible_with_XBMC)
they state that you should tick the 'Undirect fullscreen' option in the
composite plugin, or disable composite altogether.

I believe the undirect fullscreen is enabled by default, so that didn't
work, and disabling Composite will disable Opengl and parts of unity,
and disabling opengl will in turn disable a lot of other plugins.

Is there nothing that can be done?
