Add a second ethernet card (and turn on IP forwarding+NAT) and your
Linux/MythTV box becomes a router without changing anything visible to
the dorm network.  Stick your xbox off of your new "internal" ethernet
port and traffic between the two won't be detectable on the outside.

You may also need to configure some services to only bind to the
internal interface so they don't 'leak' unwanted traffic like, SMB
service broadcasts, or accept inbound connections.   You could also
use firewall rules to limit what get out to the dorm network.
