Safari problems with youtube

[Webmason]

Hello,

I am running Mavericks, 10.9.2
Safari 7.0.3
And Adobe Flash 13 (Newest as of today)

No matter what I do, I can not get Youtube videos to play correctly on Safari. They play fine on Chrome and Firefox.

The videos kinda play but are very jittery, no matter the resolution.

I would love any help I can get here, I don't want to bail on Safari...

Thanks,
Tom

I have had good results using the YouTube5 Safari extension. It forces YT to play in HTML5 so you don't even need flash. If you are on a low speed connection, you can tell the extension to use a lower res. video if you like.

I have the exact same issue.

Someone in the Apple forums posted this fix.

Safari > Preferences > Privacy
Cookies and other website data:
Press the “Details” button. A sheet will drop down.
Enter YouTube in the search box at the top right corner.
Highlight the entries and hit the “Remove” button at the bottom.
Try YouTube.

This worked for me.
