iMac Youtube Problems

[Neotribe]

My iMac has been having major issues playing Youtube videos lately. My internet connection is fine and all the other websites are super fast but when I play a video on Youtube it plays for about 15 to 25 seconds and then stops and says "An error occurred. Please try again later."

If I force quit everything and restart, it works for about thirty minutes and then starts doing it again.

It does this on Firefox, Safari and Chrome.

Any ideas what is wrong?

I have Adobe Flash 11.2 installed
27 " iMac
Mac OS X Version 10.7.3
6GB 1067 MHz DDR3

Are you running some sort of content filter or firewall? I have that problem unless I make sure ytimg.com is open in my filter.

Try going to youtube.com/html5 and turning off the trial. Users that have capable browsers and computers are apparently automatically entered into the trial, which is annoying imo.
