Maybe this has been touched on already, but I don't see it anywhere, so here I am.
Lately I've been a little more active around here, and I've noticed that whenever I visit anyone's profile, that their video autoplays. So does mine. I even made sure that the &autoplay=1 wasn't accidentally in my code.
If this was a problem on my end you'd think that it would happen on other VB forums with that plug in, too, but it doesn't.
While we're on the subject, I'd really like to suggest an option to disabling them for the time being in the User CP, at least until its fixed. I would much rather not go onto someone's profile and have the video start playing.
