[Plugin: Lightbox Plus] Cannot play video using the lightbox plus plugin

I tried several times to get this to work with both youtube and vimeo and can’t get it to work.

I tried the following:

<a rel="lightbox" href="https://www.vimeo.com/14299113"><img class="size-full wp-image-395" title="video" src="https://wp.mymoby.com/wp-content/uploads/2010/08/video.png" alt="video" width="123" height="94" /></a>

<a href="https://www.youtube.com/watch?v=VhtIydTmOVU" rel="lightbox"><img class="size-full wp-image-395" title="video" src="https://wp.mymoby.com/wp-content/uploads/2010/08/video.png" alt="video" width="123" height="94" /></a>

and 

<a class="lbpModal" title="Secondary Lightbox (Video Demo - YouTube video in iFrame)" href="https://www.youtube.com/v/pUPrCCP73Ws"><img class="size-full wp-image-395" title="video" src="https://wp.mymoby.com/wp-content/uploads/2010/08/video.png" alt="video" width="123" height="94" /></a>

I can’t get it to work.

I also deactivated all of the other plugins, removed my jQuery from the header and tried with Twenty Ten. Nothing seems to work.

All I want is to play the video in a light box! ??
