DM8168 EZSDK 5.03 - can't get HDCMOP output working?

Team,

I'm trying to display matrix-gui demo out through HDCOMP.  I've followed instructions from forum post link below.  Terminal output also included.  Eventually i want to run Gstreamer demos uisng the HDCOMP output.  Are there any other changes needed to do this or if i get it set w/ matrix-gui, i'll be set?

I tried the /etc/init.d/matrix-gui-e stop - didn't work.
Then i tried to kill it, run the sysfs commands, restart - didn't work.
