Q: My Apple TV2 won't display movies or home videos since iTunes 12 upgrade. Anyone else experiencing this?

I Have the same issue. I have made sure I authorized the computer and turned on home sharing (these were already turned on), still have this issue. No idea of a fix. Have you found a solution yet?

Sorry beta software is not support in a public forum.

I Understand,shame though because it seems I'm not the only one with this issue

That's the whole point of betas, so that someone can find issues with things before they go public. If you want things to work avoid using betas.

hi i have the same problem but i think apple need to update or upgrade the apple tv and then will we work  i not sure but  we need to contact to apple suport

I think this is one of the issues with free public betas - people are bound to try them….whereas if you pay for the privilege you'll be more accustomed to things not working as they should.

Pre-release software bugs or issues should be discussed in relevant fora not the general ASC.

No harm I guess in letting teh AppleTV team know assuming they don;t already - they don;t reply.

Waiting on giant update (which includes iTunes 12.01) to finish. Perhaps it's fixed. I'll edit this when finished.

It's just fine here.
