[mythtv-users] Twinview CRT + TV and Domain panning

I've been playing with Xorg's configuration file to get this setup straight:
Main display: CRT screen (Sony Trinitron 19")
TV-out :      TV via S-VIDEO
Twinview on
in a "CLONE" setup, but at different resolutions (as in independent resolution for the TV).
on Nvidia 6600GT
If I run both screens at the same resolutions everything is fine. (twinview = CLONE)
But I want to set the CRT at 1024x768 and the TV at 800x600. I can almost feel the victory: with my current xorg.conf file I get the TV not showing everything (only the 800x600 left-upper corner of the 1024x768 I'd say).
Now I just found out about "panning domain". Anybody knows if this is what I'm looking for ? I can't try it right now, I'll try it tonight, and let everyone know about it if it works, but I don't understand all the theory about this yet, so I thought I might ask for insight.
Here is my current xorg.conf and a commented-out panning domain that I plan to use:

Someone has done that ?
