YouTube videos not playing?
One of the following steps should help.
1. Install Adobe Flash Player.
2 .Are Plug-ins Enabled?
Safari > Preferences > Security
Click in the box for "Enable Plug-ins".
3. Check whether you are currently in YouTube HTML 5 trial.
At the bottom left of the page uncheck the box for
"You are currently in the HTML5 trial".
Now try YouTube.

Also, I don't know if it would help but we tried to open youtube from my mom's macbook pro and another macbook pro and it still didn't open. However we can access youtube from our iphones and ipad.

Alright, I figured it out and solved it. Just in case there's someone with the same problem:
I just wennt to go > go to folder > /etc
found the hosts file.
dragged it into simultron to open it.
found the two lines for youtube.com, deleted them. Saved it and it works!
Thank you to all who has tried to help :O)

You wrote above that you had changed your DNS settings, so I assume you know how to do that. In your router, change the DNS settings to use your ISP's DNS servers. Usually all you have to do to make that happen is to delete whatever you put in. The DNS server addresses should be populated automatically.
On the clients, also remove the DNS server addresses. Your router should then be used as a DNS proxy, which will refer all queries to your ISP.
Test. If there's no improvement, please repeat the Network Utility tests and post the results.

Hi. I have the same problem. My macbook pro doesnt open youtube in any browser (safari, chrome, firefox..). I tried the solution you gave us here but i cannot save the changes in the host file. Actually the file was locked to change anything but i gave permission. Then still it doesnt accept any change in the file. I am trying this on Textedit because I dont have smultron. So is there any other way you know, to solve this problem? thanks.

Hi! I had the same notice, so I didn't want to mess with it and used smultron, here's a download link for it, I think it'll work if you open it with smultron and let you save it :O) Here, give it a try: http://www.macupdate.com/app/mac/15114/smultron
