Apple TV Buffering issues

We have a client that has approximately 10 apple tvs wired and used to cast movies from thier laptops/ipads and are having alot of buffering issues.

The network is gigabit ethernet and is fairly flat.

Is there any sort of protocol that needs to be enabled on the router/switch to allow maybe multicase or something along those lines?

You can try changing the DNS setting in the Apple TV to point directly to the router IP address.  I've heard that helps with buffering issues.

The DNS thing is worth a try... but I'll mention that I happen to know even the Apple Campus in Cupertino has problems when many AppleTVs are connected to the same network. It's not terribly unusual for this to be an issue. Might be something Apple has to address in a forthcoming software update.

Don't have multicast enabled.  Will try changing IP's to static and change DNS settings.
