Can't see mounted disk images after mountain lion upgrade

So after I upgraded to mountain lion I can’t see my mounted disk images in media player anymore. 

Prior to mountain lion I have my apple tv connected to my imac via AFP and could see all the HD’s etc. This was a great way to keep certain files out of the eyes of my little ones. I could watch them by mounting the image on my computer then it simply showed up when I connected. Now its simply no longer listed. 

I’ve restarted everything, removed the share and re-added it. No go it still doesnt’ show up anymore. :frowning:

Any idea’s?

Running 10.8.2 and latest Atv versions on 2nd gen Apple TV.
