Apple TV Update 5.1 has broken my home sharing (I think)

So, last week, I updated my Apple TV to it's newest firmware - 5.1. Since then, my home sharing has not worked.

Well, on the Apple TV, it sees my MacBook Pro, it sees my library of music and movies, but when I go to watch something or play some music, the Apple TV never stops loading the content.

My itunes is up to date, I have Mountain Lion, and my Apple TV is up to date. All other services like Netflix work great on it, just not home sharing.

I read there was an issue with home sharing and Mountain Lion, but I have never had this issue until I updated my Apple TV.

Anyone else experiencing this and have any thoughts. Watching my shows and stuff at my computer desk is kind of crappy.
