Windows 7: Unable to view online videos

I have a windows 7 64bit laptop and a window vista 64bit laptop.

I seem to be unable to view some of the videos on the windows 7 laptop but able to view those same videos on vista laptop.

the error is normally "200, Stream not found, NetStream.Play.StreamNotFound, clip". Is it a settings problem as both of my laptops are installed with the same version of flash players.

I have tried to uninstall the flash player and re-install the flash player but the error still persist.

Hi and welcome to Seven forum.
Are those videos from Youtube or similar online places you are having a problem with? What browser do you using?

i tried using IE, firefox and chrome. all of them could not assess the videos.

youtube videos are all okay. no problem with them. coz i watch animes online for example Aquarion Evol Episode 22 English Sub << this site. the first video on the list i could not watch but the 2nd video on the link i could.
