How to elimnate menu tabs for video content?

I have a Windows Media File uploaded that plays fine using either the nav tab above my thumbnail or the play link below the thumbnail.

I turned off the menu tabs in Settings/video, and the clip no longer plays. Clicking the play link below the thumbnail redirects to the the theme greeting page. If I turn off the links below the image, however, the clip will play OK using the menu tab above.

How can I get rid of the tabs? It's redundant to have both links and tabs, and I really prefer the cleaner look of links below the thumbnail.

I'm running a modified version of box_cleanslate.

Thanks.
