Smart YouTube Pro – Justification problem

I appear to have a conflict between the WP Template i’m testing and YouTube Pro. I am hoping someone may have an idea on how to see what’s causing this issue.

When using them “Alyeska” from Themeforrest, the justification of the YouTube video is lost. It should be centred but it goes to the left. The text below the same video is still centred.

I switch back to default theme and it’s fine, so it appears to be a conflict between the Plug-in and Theme. Any ideas?

Thanks in advance for any pointers you may have.
