I've been having problems with YouTube over the last couple of days. Most of the time it works just fine, but it's freaked out a few times, and not worked for an hour or so, and then gotten better. Here's what happens: The pages looks like this (YouTube homepage), and videos won't play (annoyingly enough, page-ads play just fine). It tells me that my Flash player isn't up to date, which it is. Other flash-things work just fine, including other video sharing websites. Google Chrome is my primary browser but the same thing happens in Firefox. I've asked around and no one I know has had the same problem. What is wrong and how can I fix it?
Why don't I get sound when I play YouTube videos? Quicktime videos work fine. [more inside]
