HELP YouTube problems!

Hi there
I posted last night on a local THai forum but have decided to come to Macrumours for more expertise.

I shall simply copy my posts to fill you in.

....after someone mentioning Flash I wrote

....and after a suggestion to swap to Youtube HTML5 I wrote

So the Macbook runs everything but Youtube at home but runs Youtube at the MAc shop.
The iPad seems to run slowly for Youtube......it may OR MAY NOT have a problem...iPads are often slow in my experience.

I really hope someone can help
Thanx, Cheeryble

 

Wow no answers...

OK since yesterday I've tried this also.
Connected to my router by ethernet cable direct. No good.
Downloaded Chrome and try Youtube. Again page loads but video doesn't.
Unchecked "Predict network actions to improve page load performance."
No good.

Still love some whizzbrain to help!
thanks

 

By way of a bump, I also rebooted.
Help!

 

OK a real discovery!

After calling my provider yesterday and being told to turn off my router, they'd reset and call back in half hour, 75 minutes later I just left the house.
In the evening I called again. Oh they'll call you tomorrow. Yeah right.

But my brain started working on this problem of why the speedtest seems good but no Youtube.
I googled for alternative video sharing sites. Found Veoh and Vimeo for just two. Then remembered there are also porn streaming video sites.
So I tried Voeh and Vimeo and they both load fine.....and tried Redtube and Youporn (purely for diagnostic purposes!)

THe results?
Veoh and Vimeo and Redtube load fine. Youporn doesn't load at all. And of course my real problem (as I work from it sometimes) Youtube doesn't start either.
Strangely whilst yesterday it would sometimes go to the Youtube page OK but not load, today it won't even get to the page "The connection has times out"

Also odd I notice Youporn is nothing to do with Youtube as a company and I see that for Youporn my browser is trying to connect to w3.mict.go.th.....a Thai site presumably (again I'm in Thailand......Perhaps Thailand has banned Youporn and it's a separate issue....maybe I'll try with a proxy server).

I've tried clearing all cookies etc.

Hmmmm

 

Tried opting in in Safari (usually on Firefox).......didn't work I'm afraid.

 

More real info..
Took my Macbook out and hooked onto WiFi coming from an ice cream parlour.
Within a half minute I was downloading Youtube no problem at all.

So it's nothing to do with my Macbook.

What can it be? Any sort of router setting? Or the provider? (even in Thailand which has been known to ban sites like Youtube temporarily at least I have confirmation that others are getting Youtube freely and of course the ice cream parlour had it and the Mac shop last week. So I think it's not likely a regulatory problem)
Seems to me it's one of the two....
