My mistake
We're talking about two different things
I talk about Enhanced Movie Center, which has the support in the skin coding.
( only HQ skins on BH addons server)
Advanced Movie Center is impossible to code in 1920 x 1080 format without change in the plugin.
I do not intend to do other people's plugins.
So, the only option for Advanced Movie Centre is to use older skin with format 1080 x 720
And as a good alternative is Enhanced Movie Center
which is as far as I know the continuation of work on Advanced Movie Centre.
