Unable to watch videos on youtube when logged in account

I have pretty strange problem with YouTube. When I just go on YouTube and
watch any video through Firefox, Chrome or Chromium (I tried both Flash
and HTML5) - it works perfectly.
BUT! When I log into my Google account and try watching video from my
account - video can't play. It just shows me 'rolling wheel' icon on
screen (as if it downloads).
I've done this test on the completely fresh system without any changes and
on system with some drivers both. I had that result on absolutely all
distributions of linux that I've tried (Ubuntu 10.04 LTS, 12.04 LTS,
13.04, Mint, Fedora, OpenSuse).
So, where the problem could be?
