I don't know if you are also getting the same problem that I am getting nowadays with youtube after it got it's new player. Well, I am getting the problem that,when I go to watch some old videos then it says that 'the video is no longer available,Sorry for your incnvenience' or something like that. If you also get this problem then I have found a solution for it. When you get such message in player then just go ahead for another video in related section and after that page is loaded then simply again click 'Back' button in your browser.And your video will be loaded. I got it success in my IE6 but don't know about other upgraded versiona nd other browsers like mozilla, opera etc. Thanx
