Video Title not linking when there is a ' in the title

Hi, I tried your plugin (which is great) on a test site.
I have now bought the plugin and installed on an almost identical site.
When I add a video with the title as follows:

“Here is a video, let’s hope you like it” the link does not work from the Related Videos section

(it does work on my original test site)

Changing the title and removing the ‘ from let’s i.e.

“Here is a video, lets hope you like it” works.
