Yep, the resolution of an analog tv is not very good, even compared to
the worst monitors out there.

you don't need two x-sessions or two gdm's, i have one session with two
displays :0.0 for my monitor and :0.1 for my tv.
To run myth on the tv:

export DISPLAY:0.1 && mythfrontend

Look at my XF86Config file (attached)

Have you read the file ivtv-fb.c?  The begining of it is a HOWTO on
setting up X to run this way.

good luck
