is there an easy & quick way to block a list of MAC addresses from

but if you have some good switches its simple a matter of config the security

Switches would be a good solution but their cost is quite some money.
I think iptables has a solution:

iptables -A INPUT -m mac --mac-source 00:0F:EA:91:04:08 -j DROP

If applied to tjener, this would block all traffic coming from that mac, thus blocking HDCP and DNS.
The pc with that mac would have a hard time getting on the network and internet.
To find an easy list of mac address of your pc's you can use a (windows program :-( ) called angry ip scanner.

Hope it helps,
