Pro Presenter
 

I Get this error trying to use a .mov

"A visual context could not be established. This is likely due to the presence of a non accelerated graphics card (i.e. AJA or Blackmagic)

You may be able to disable the cards desktop display."

Ideas for help

Did you get this figured out?
 

Did you find a solution? We just started having the same issue in ProPresenter when we updated the OS to Mountain Lion.
