Actually, it's a good sign that they don't work on that other site either. It means that the problem isn't with this site (which I would have had a very hard time to help you with) but it's something with the settings on your computer instead (which we can fix a lot more easily).
First thing to do, in Explorer is this:
1) Choose Tools > Internet Options.
2) Click the Advanced tab.
3) Scroll to Multimedia.
4) Select Play animations.
You may have to quit Explorer and reopen for that to take effect.
If that doesn't help, then another possibility is Zone Alarm. Do you, by any chance, have that on your computer?
If you DO, then you need to go to: Privacy pane >> Ad Blocking >> Custom
and Un-check animation
Let me know if this helps out at all. If it doesn't I'll keep looking.
