Copy movies from iTunes 11.1.3 to my AppleTV gen1

Hello.

At the new iTunes I can select the movies to copy to my AppleTV Gen1. Sometimes when my computer is turned off y use the AppleTV Gen1 to watch my kid´s movies. 

I just updated to the latest aTV Flash, I can see the AppleTV Gen1 but I can´t select the movies to transfer (copy).

 

Greetings,

 

Ricardo
