Does Internet Explorer play videos?
On Firefox, go to any random video on youtube. Right-click on the video and press settings, there should be a little window that shows up, on it there should be a check box with the words "enable hardware acceleration" or something similar. check it, or uncheck it if it was already checked. Exit Firefox, open another video, and see if the problem has been resolved.
Good luck,
Thank you very much for your reply.
Internet explorer does play videos but it is a real pain in the arse mismatch for speed, use and could cause a possible confliction I had before which some online tech guy took 30+ mins to sort out a bring my comp back from being a brick. I still don't understand even now but I know I was told I should just not use it! I tried what you said the box was already ticked, I un-ticked it came out went back, did'nt work, re-ticked it went out again just to clutch at straws but it did'nt work. Same as usual: in you tube it says 'An error occurred. Please try again later'. With everything else it is just blank where the vid should be?
Any more ideas please.......
