Thanks although those topics are complicated for me to understand. The reason I bought X theme was to avoid too much coding work as this is not my expertise, and yet these help topics you have linked me to talk of jquery and other things, which seems to be getting a bit over involved for my purposes!
Firstly, I understand that black bars appear when the aspect ratio is incorrect for the video container. I have tried one of the solutions set out, where 100% is the chosen option, but it seems to only work on a large screen. Secondly, the jquery handler whatever that is, where does this go?
And finally, could the video element not be made more useful for videos that are from external sites? Most videos are not hosted on the server due to bandwidth, so I don’t really see how the video is handled better in X theme than just how Wordpress does so natively.
I’d appreciate an example and some hands on help to get this problem corrected, as I’m sure others would benefit from the solution in the future.
Thank you
