I tested the two mheg samples on two systems running builds of master.

One has v33-Pre-509-g7ea05dd532: the mheg screens can be seen by 
pressing F2 and navigating around, using both VAAPI and OPENGL playback 
profiles.

The other has v33-Pre-733-ge0996cb499 and I cannot get the mheg to 
display anything, pressing F2 or F7 has no effect, on both OPENGL and 
NVDEC profiles.

Have I messed something up or is MHEG broken in the latest master?
