Looking for a member plugin that restricts only selected content

Hi,

I have a video website. I want some videos to be available to everyone and restrict premium videos to members only. I tried wp-members plugin. Unfortunately, it does not restrict the feature image, which is the area my theme puts the video. Most video themes put the video there or in the header. So I am looking for something that will specifically restrict videos on a post by post basis to members only. Does anybody know of a member plugin that will do this?

Thanks
