Two different YouTube embeds become the same video after pressing the browser's back button!

Hi everyone!

So I've been having an issue with the video embeds on my site.

http://acoustagrip.com/

So first I click on one of the items in navigation and visit another page on the site. Then I click the browser's back button. When I return to the home page, the video embeds both display the AcoustaGrip CELLO video instead of the two different videos of the Shoulder Rests and then Cello Pads farther down.

When I reload the page, the videos go back to being distinct like I intended. Both are embedded with iframes. Is there maybe a better way to do this so that this problem doesn't occur? Any ideas what might be causing it?

Thanks in advance for your help!

Regards,

Dakota
