I'm using a mask in my projector Display Template (DMX 2004)
and it works perfectly on the PC. However, the Mac version (OSX) of
the projector has the mask 'slipped' up by 15-20 pixels or so - my
'visible' elements of the movie are all cut off at the bottom with
the movie background base colour displaying at the top.
The only clue I've been able to think of is that the Mac is
running a widescreen desktop and maybe it's a PAR issue? But if so,
why is the mask being treated differently to the projector (which
looks OK) and how could we anticipate what flavour of Mac a user
It's annoying as the projector seems to work perfectly apart
from this issue.
