I have changed the site design to make it full width (I changed the site Outer Padding to: "Extra small"), will this help you?
Does your page support Index Page?
I'm not sure what you mean. The York template I am using supports Index page, I found that much out.
If it's easier, I can change my site design to make full width videos easier to enable. let me know how I can help/whta I can do
Thanks for your advice so far
