On site video playback issue
 

If you go to site with Firefox and click image it takes you to that image page, click that image and video opens in like a private slate gray play on site page.
If you go to site with internet explorer and click an image that takes you to image page, when you click that image it opens video in windows media player on your computer.
Would like to fix it so when you go to site with any browser and click image it would go to post page with video to play on that page like most usually do.
Can this be fixed without major FUBAR issues?
Can this be fixed without changing theme that I have put so much work in?
It is word press adultskin video theme, same one suggested here in the gfy forums.

Resolved the issue ( I think ) was missing a bit of code per post. Now to edit all of them.
