Cisco Wireless :: WLC 5508 - Bonjour Snooping

Have 7.4 installed and configured for Bonjour Snooping. All is working, but working too well. We have a large campus that house 2 schools and each school is complaining that they can see the other schools Apple TV devices.
 
I have played around with a few different scenarios to see if I can localize the bonjour traffic. I guess I am looking to create a logical split for bonjour devices among the schools. Apple came to the school and informed us that the I PAD has a limit of 64 devices that can be seen via the bonjour. At some point we will have over 100 Apple TV added.
 
so we have 3 wlc 5508's with 7.4.100. we have 2 SSIDs that span the whole campus using AP groups to segment the floors in buildings. So the schools are logically split with AP groups.
 
Here is what I have tried, I created few mDNS profiles and assigned the services for Apple TV - let's call them school1 and school2. I assign the mDNS profiles to the interfaces dedicated each school. Enable snooping on the W LAN with profile of none. The end result is that devices from both schools can be seen.
 
I tried to create new ssid for apple TVs and a new ssid for 1 schools teachers. I followed the v lan select example [URL]. End result is that devices from both schools can be seen. I have tried the mDNS without multicast enabled just like the video shows to no avail - I assume maybe my AP groups might be more complicated then the example of just 2 v lans. [URL].
 
I have tried combinations of things, but I must be missing something . In the webinar, Cisco said it will use filtering to restrict which  clients can see which services (Apple TV's, etc). What will Cisco use to  filter Bonjour requests? According to this article
[URL].
 
The filtering options are: · Per W LAN/SSID · Per V LAN or AP  Group · Per Interface Group (which is a group of V LANs pooled together). A Bonjour service policy can be created and applied on any one of  the above criteria. In the future, we will support per-user Bonjour  service policies which will come as a RADIUS attribute from the AAA server. Read more: [URL].
