YouTube problem
I posted this in OS X Mountain Lion but it seems that nobody knew the solution.
I am having this weird problem and I'm not sure whether it's problem with OS or Safari, but almost every time I open some video on YouTube it starts without any problems and then after a moment video stops, the progress button goes to the start and there's wheeling 'loading' ring in the middle.
I tried re-installing flash but it didn't work and I don't know what to do, it's very frustrating that I cannot watch even 40-second video. I also noticed that when I refresh the page, the video stops in the same place as before, maybe it means something.
I also have one smaller question, why YouTube on Safari and Opera looks different? Can I change the YouTube layout on Safari? Here are print screens to show what I mean:
