Fix for embedded videos on the forum?

Hi, Linux user here without Flash installed, just wondering why this is the only site I frequent where embedded Youtube videos always say that I need a plugin to view them.

The videos on the main site load fine as HTML5 videos in either .WebM or .MP4, but every video on the forum seems to request Flash. This is the only site I frequent where I see this behavior.

 

I example, If I posted a link to the same video here and on lets say DSLReports.com's forum the video would be playable there for me but the same video here would only display as a plugin notice.

Dunno, but this would probably be a better place to post this question:
