If your tv is getting a link-local address you should be good to go.

Just edit your ETH0 section in /etc/interfaces to read:

auto eth0
iface eth0 inet ipv4ll

ip4ll is a relatively new option for telling the interface to use a link
local without waiting on DHCP to timeout.

You could set a static in the link local range as well... if the tv is to
spec, it will check to see if the address is free before it assigns one, so
you shouldn't run into a case where they get the same address.  A static IP
may be required, I've never run Mythbackend on a box without a one.
