Set 'X11Forwarding yes' in /etc/ssh/sshd_config on the backend, then ssh -Y
into it from the frontend. Running mythtv-setup from that ssh should result
in it being forwarded over SSH to the frontend.

Can't see why you would.

ISTR the 8k fix went into 0.22, as I backported it to my local copy of 0.21
to avoid an upgrade. I think <http://code.mythtv.org/trac/ticket/7688>
contains the small patch I applied, and it's 22 months old.
