"Automagic" is wonderful, when it works.
May be time to try a manual xorg.conf.
I've reused the same xorg.conf since Dapper days, rather than fight with 
reconfiguring each time I upgrade. Currently 10.04 with nvidia compiled 
from source and working fine.

I've always used two xscreens while working on MythTV so I can work from 
the LCD and look over at the TV to see the result.
Never tried TwinView so I have no idea how to make it work.

My (ancient pos tube) TV is connected via Component and I have to use 
some custom Options to make it work.

Some Options are deprecated now and x simply ignores them.
cat /var/log/Xorg.0.log to see which are ignored.

Once I have everything working, I comment out the LCD portions of the 
xorg.conf. Once I'm satisfied it's stable with just the TV, I remove all 
the commented stuff to tidy up the xorg.conf.

(this is an older version. I've since trimmed out unused resolutions and 
depreciated options)

When setting up dual xscreens on a new frontend (dual LCDs), I ran 
nvidia-settings to get a baseline xorg.conf, that didn't work, then add 
monitor specific info (resolution, refresh, etc.) to each screen until 
it does.

iirc, 9.04 has that absolutely hateful 'failsafe' x that automatically 
falls back to a default lo res screen if the custom xorg.conf doesn't 
work. Impossible to work with so I disable it.
All the tweaking is done from a terminal so you have to be handy with a 
non GUI editor like vi.
