Ok, I don't know what's going on here, but, if a video doesn't play all the way through the first time, I have to close Firefox, and literally try 3 or 4 more times before the whole thing loads. And it seems to alternate, at random, between Windows Media Player and Flash, despite the fact that I selected WMP as my default player. I have all the latest codecs downloaded, and this is really annoying. If anyone can help, please do!
