I am not sure but for what i have experienced in my Xperia S (i am still able to install the Adobe Flash Player 11.1 by Market), but gives alot of trouble with movies playback, for what i have experiencied and try, did you already updated the version of your youtube app?

[mridulksinha]

yes I have already updated the youtube app,moreover the problem exist with all the apps like live TV where web player is required.I hope the problem is with the flash player but dont know how to fix it.I can only download and install it.Any way thanx for your help.

Its a bit strange, since the movies are loaded in HTML 5 and not in Adobe Flash, that's why i was saying if it was a problem with the Adobe Flash being installed (because sometimes the mobile can try to use in 1st instance the Flash and next the HTML 5), i hope someone can give you a best answer, but in last case, i would say to you to delete in the internal memory storage "card" the default and temporary files and then reinstall your phone.

This sounds like it has to do with which protocol that is used. Streaming of video for mobile devices often use a protocol called RTSP. I've heard of several cases where old routers doesn't support/allow this protocol.

If possible, try using another internet connection and no/other proxy and see if it works.
If you have access to the settings in the router you're connected to, try opening ports 554 and 8554 in its firewall.
