Video embedding on other websites problem

Hey guys,

I hope there isn't a thread about this problem yet. I used the searchbar before but couldn't find anything.

If I try to embed ns videos on other sites with the code from the "share" tab I get no video with Windows XP and Firefox V17.

For example this link: https://www.newschoolers.com/videoembed/600875
It's just blank with xp/ff17.
It works fine with my other setups (win7/ff/opera/chrome/ie, xp/ie, mac os x/ff/chrome), the video shows up as it should.

Anybody else who got this problem and can confirm it? I tested it on two different computers both with xp/ff17 and it didn't work on both.

Would be really nice if the tech admin could have a look at this!

Thanks!
