Slide slow to load for video
I'm having a problem with parts of a Presenter presentation taking an age to load and appear. I have embedded a video into a presentation sequence and the rest of it loads ok, but when it gets to this slide, takes an age to load.
It is supposed to look like this
In other cases where I've had the backgroud of the slide in the Master slide , it will load without the Background and only appear after a while.
Can you please tell me how to get these to load as intended.
