My first impulse was to say: the message simply means Youtube deleted the video. Perhaps it violated some copyright, or the uploader removed it himself.

But you have obviously tried a lot of the solutions suggested (GWA, Flash).

Other things to consider:

1. Are the uploaders limiting the video to certain geographic locations? Your time zone suggests you are located in the Middle East or Eastern Europe. (You can solve this via the Google translate 'proxy' server.)
2. Have your friends tried to bring up the 'high resolution' version of the video?

Please give examples of videos your friends cannot watch.

not delete it I can see video they can working,try this
YouTube - WTC - 9/11: 911 5th Anniversary Memorial Music Video 9-11-01

I saw a similar problem on Neowin, but the user was able to see the videos fine in a different browser, I think. If I can find the topic, I'll link to it here, or post what their solution was.
