The first thing you want to do is setup a fixed IP for you Ceton.
There are 2 ways to do this...either set it in the ceton's web
interface as a static address, or get it from a DCHP server. It sounds
like you've set it for DHCP, and based on your comments it sound like
you've been successful in getting this working, and you just want to
lock it down so it's predictable. Is your DHCP being handled by your
router or by your mythbox (or another server on the network)? Most
people tend to have their router to the DHCP. Almost every router I've
ever used has an option for fixed DHCP assignment. Generally, you go
into a config page somewhere on the router and you specify a hostname,
MAC address, and IP address, and whenever it gets a DHCP request from
that MAC address it will assign it that IP.
