I have set up a low-end machine with a TV adapter to run MythTV on the assumption that I wouldn't need X running on the back-end machine but I find that the mythtv-setup programme is graphical! So I need to install a lot of X packages just to run the setup.

I didn't know that. Well you learn something new every day.
There's a potential confusion of terminology, in that the "X server" and "X client" are the opposite way round from what one's intuition thinks.
If you're sitting at a machine whose display is running X, and you're looking at windows displaying X applications running on a remote machine, then your machine is the server, and the remote machine is the client.
The logic of this is that the X application needs display resources, so it requests them from the server and thereby acts in "client" role. he machine you're sitting at is supplying them (so that you can see them) and acts in a "server" role.
Your intuition, however, will tell you that you have requested the remote machine to run the application for you, so you're the client (for the application) and the remote machine is the server (running the app for you).
That being said, Tim's statement "You don't need a local xserver to run X applications" could be misinterpreted.
YOu certainly need a local X-server to display an X application, otherwise you won't see it (and the machine running the application will probably refuse to play if it can't succeed in soliciting X resources from your local machine).
But you can certainly run X applications on your loca local machine, and have them displayed elsewhere; in which case your local machine does not need any "X server" resources.
Best wishes to all, Ted.
