Ways of triggering video and how to play in section of frame

I would like video to play in a small section of the screen so that I can have pictures and text visible at the same time. Currently, it seems that the only way to achieve this is to create video set into a larger background and then put this into prezi with the other elements on top.

Is there a better way to trigger video? (using the arrows)

I am a little worried at the flakiness of the video player. I am beginning to recommend this to clients and the more I do the less it seems I can trust the video player - controls don't work, can't pause without restart - nyway if you can answer the question above it will be a start

Thanks
