That is not a good reason to run a telnet server, and for two reasons:
Firstly, it won't do what you seem to expect - for this sort of remote
control application the thing you're controlling (MythTV in this case)
/is/ the server - you simply use a telnet client to connect to it.
Secondly, you wouldn't sanely leave the MythTV interface open to the
internet, you'd have it listen on the loopback interface, ssh into the
box from your remote location, then run a telnet client on the Myth box
to connect to MythTV itself.

Then either use two separate ssh daemons (eg one on port 22, one on port
222) so that if you lock youself out of one you can get in via the
other; alternatively if you want a completely different access method
then consider something like OpenVPN.

What happens if the box gets cracked while you're in Japan and there's
no-one locally who can do the reinstall? It's not worth running telnet.
