I have problems with youtube. Video and sound lags all the time.
- Normally the video loading to finish. Now not, beginning about 50 seconds, and then it stays there. When I watched 50 seconds, the video stops and start the loading a little farther, and the video stuck to the end.
- HD image is not possible to watch, especially in full screen mode. Just terrible.
- loading bar "flashing" (appears and disappears)
- Vimeo and other services are operating normally.

The problem has been more than a month.

The Friends have no problem with YouTube.

Can someone help? It would be nice to watch videos..

If you mentioned your browser it wouldve helped

Thanks Brain!

Now it is a little bit better. Picture and sound works quite well for the loaded area (still not normal). Video loading a little bit better (still not normal ).

HD video still can not watch.
Oh, and the problem is in all browsers (I use chrome).
