Youtube Problems

Hello,

I dont know if this is Youtube's fault or Safari but these are many problems I experience

Sound: If I am watching a video, and I back out half way through. The sound will still contiue to play from the video even though im on a different page

Comments: 50% of the time the comments will never appear, all I get is a infinite "Loading Comments" sign

Randomly stop loading: I have fast internet, entire videos will load within 5 seconds on HD. However sometimes the loading will stop half way through, the only fix is the click on the timeline 1 second after the time it got stopped atand it will load the rest of the video instantly.

Power saver for ads: Sometimes powersaver will try to stop the ads on youtube videos, if i click to allow the ad to play. I will get a grey fuzzy screan saying "an error has occured" and Ill have to reload the page and hope the power saver option doesnt stop me again.

Thank you!
