Watching video clips

[Manchikeri]

Hello Ladies and Gents!

Suddenly, and for no reason I can discern, my pooter will no long play video clips.

I am using W7 (64-bit) with SP1 on a Sony desktop. I have tried using all the W7 "trouble shooters" I can find but without success.

Has any kind person got any suggestion how I may solve the problem, please?

Thanks in advance for your help.

Are you talking about videos already on your computer? If so what program are you using to view them and what type of file are they? If you are talking about You-Tube type streamed videos what browser are you using?
