Youtube "This video is currently unavailable" in Safari 6.0.1
So I've had this problem for a few weeks now and it's been driving me up the wall, but after fruitless internet searches in an attempt to solve it I've finally decided to submit a support ticket.
This seems to be a widespread issue, but on my iMac running Safari 6.0.1 a lot of videos in YouTube won't play and come up with the message "This video is currently unavailable". I can however view these very same videos without issue on my Macbook (running a lower version of Safari) or on my iPhone.
Someone please tell me how to fix this as it's driving me crazy!
