Home sharing not responding after last update in ATV2 and 3

I used to watch my itunes library content with home sharing in my ATV's with no problem, listen music, watch movies, etc, but since last ATV update I can't access to my Itunes library (home sharing), I followed and read twice your troubleshooting articles, and nothing happened. I'm in the same wifi, same Apple ID in Itunes, ATV's and in my iphone Remote app, I can use the airplay with no issues, but not directly from the ATV home sharing, message in the ATV: "Could not connect to (my library), Make sure, blah blah blah...". I have that latest versions of itunes, ATV, Iphone IOS, etc, I read all your blogs and nothing seem to be working. Hope anybody can have some answers. I try in both ATV2 and 3 with same results.
