View Videos from a post without clicking 'Read More'

Hi there,

I’m having a few problems trying to get videos to show up from a post. I have to click the ‘read more’ button to view the video.
I’ve tried several ways like a plugin for featured video and several other ways, but still having trouble getting it to view.
I didn’t have a problem with my previous theme which makes me think it’s a setting with the theme somewhere.

Thanks

Liam
