Apple TV was working fine up until yesterday.
I had rented & watched Men in Black 3 and it was all good - that was my first day experience wi Apple TV - great!
Now it's all gone downhill...
Nothing changed on my network - connecting wired directly to my router/modem to the net.
Apple ID is fine as i've tested it on other iDevices.
I have the iTunes Store set to Australia with correct Time Zone.
I've got Home Sharing turned on with my Apple ID on the Apple TV and it's working.
The problems ...
When I try to Sign In, I either get (it's random) ... 'Unable to Sign In - Apple TV can't connect to the server at this time. please try later.', OR 'Unable to Sign In - The Apple ID you entered couldn't be found or your password was incorrect. Please try again.'
When I try to watch YouTube I get ... 'No content was found - There is a problem communicating with YouTube. Try again later.'
Funny thing is everything else works - Movies & TV Shows previews, iTunes Festival, Trailers, Vimeo etc.
* ? Any ideas guys?
FYI - I'm with iiNet (Australia).
