Sound for the videos at the bottom of the forum page...

[speechteachri]

For some reason, I am able to get sound for the ad part of the videos at the bottom of the page here, but I am not getting any sound on the actual videos themselves. Curiouser and curiouser.

I'm trying to do my part in watching them, since I know SR gets credit for them somehow, but I'm wondering if it's just a glitch with my computer, or if there is a problem witht he audio portion of the video?

Thanks.
