Hi Hi Danny_DeLoach,
I hope you are doing fine
Are you playing Video from slideshow module or Library module, because if you are playing videos from Library module in full screen it won't, it is a known issue on which we are working, and most probably will be fixed in next updates of LR.
As if now you can go ahead and play videos in full screen from Slideshow module.
Thank you, Rohit. I'm glad to know there is a workaround. However, I hope this will be resolved in updates that will be coming out soon, because the current workaround is cumbersome.
I have a question - why is it that when I set up a slideshow of a holiday trip, with photos and videos, and finally play the slideshow, the videos are not played at full frame ie. the size of the video displayed does not fill the screen like the photos do. Even after selecting Zoom to fill frame, there is no change. Any help? Many thanks. I have quite a lot of videos to slideshow in addition to photos!!
