Playing music videos on Extended Desktop screen

[PaulK]

Thanks for the quick reply, but this doesnt solve my problem.

My singers display works on the extended desktop screen, no problem and I appreciate that the 'video' display screen appears in exactly the same place.

What I am saying is that videos are not reproduced on the extened display, you can hear but not see them. Whereas if the video screen is on the primary then you can see as well as hear the video.

Thanks again
Paul
