I output to Full HD video/ resolution 1920x1080 and codec h264 good but no everybody can't play it

I would like just to know how can I produce a SlideShow on Video or memory stick good enough for everybody ?? I am new to the program and I like it but at the moment very confuse…HELP!

“Everybody” is very hard to satisfy. Some computers can’t play FullHD content at all. To make it playable at as many destinations as possible, please use a custom video export with these settings:

Your help it is greatly appreciate Bastian, however I having serious problems to be able to see the setting you suggesting. Could you please write the setting instead? Regards Clem Oliver

Also I am aiming to clients that wish to watch their weddings on television and or playing the slideshow in kind of older players?? Thanks again Clem Oliver
