Hm... actually, I can... but I even don't know how the video is rendered in C2. It's definitly not using a normal _video_ tag 'cause it works fine in FF.
It will look odd to come to FF guys and tell "hi, I have a problem with some third-party game engine. I don't know how it work, but it's your bug for sure", isn't it?)
IMHO, it should be better if someone from your team, knowing what's inside the "blackbox", inform FF team instead.
