Streaming Imported Content from MacBook Pro iTunes to AppleTV

I am attempting to stream my imported content from my iTunes Library to my AppleTV. In the past I had no problems, the Computer Icon/Tile was there and I could watch my content no problem. Now, the New AppleTV app is there and I don't have access to my imported content, i.e. Home Movies. Some if not all the content that I imported is NOT available on iTunes.

Please help!!
