as of lately I can watch videos, but then I click on one and it just shows a black screen and I can wait forever and it won't buffer or do anything at all. then every video I click after that does the same thing. so I go off and come on later and it's fixed then it happens again. well it happened last night and I went back on today and it's still *Can'tSayThisOnTV*ed up. so why is youtube doing this? anybody else have these problems?
