Is there any reason Vimeo won't play on my Apple TV?
Totally properly logged in.
My Vimeo account appears on my Apple TV, as do my videos.
I just can't play them through the Apple TV.
Vimeo works fine on my laptop.
My Apple TV is first generation.
The 1st gen, big aluminum box, didn't have access to any 3rd party content apart from Youtube (which google removed support for when it updated it's API).
If you have a small black box then it's a 2nd gen. Providers have started to drop support for the channel based access available on that model so it's best to contact Vimeo to inquire if they still do.
