What the issue was about: YouTube app installed from Google Play Store won't load movies. It starts, shows miniatures, when you tap it, it pretends to start loading (rotating loading symbol) and then it show information that app has to be shut cause it stopped working, it was even worse with "weakly" performing flash (no matter if I use android browser, nor firefox beta).
After a quick research I found Dark Elf thread with a solution, and link to an apk file. It helped, but - every time I tried to change volume, a pop-up've showed up saying that YouTube app stopped working, even though it wasn't running foreground. Pretty annoying.
I did deeper research this time, and tried several found solutions. I found this thread http://forum.xda-dev...d.php?t=1529715 , but the newest version didn't work either, I dig deeper and found perfectly working apk! It could be found here - http://d-h.st/users/...d_id=5366#files - YT_4.1.47_v1.apk
Direct link - YT_4.1.47_v1.apk - 6.06 MB
What you have to do is uninstall YouTube app you've already installed, restart, install YT_4.1.47_v1 (I recommend another restart), and that's it.
It looks good, works great.
UPDATE - in most cases you'll need special app to uninstall stock baked YouTube app, like SD maid, or Root Uninstaller (easily found on play store).
I hope this helps anyone.
All thanks to theos0o from xda developers.
