What i did was use the "multiple screens" configuration, detailed (sort 
of) in the NVidia readme.  Here are the relevant parts of my 
/etc/X11/XF86Config:


-----------------------------

Section "ServerLayout"
         Identifier     "asshat"
         Screen          0  "Screen0"
         Screen          1  "Screen1"
         InputDevice    "Mouse0" "CorePointer"
         InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

         Screen      1
EndSection


Section "Screen"
         Identifier      "Screen0"
         Device          "nvidia0"
         Monitor         "Monitor0"

"800x600"
  "640x480"
         EndSubSection
EndSection


Section "Screen"
         Identifier      "Screen1"
         Device          "nvidia1"
         Monitor         "Monitor1"
         DefaultDepth     24
         SubSection      "Display"
                 Depth     24
                 Modes     "1024x768" "800x600" "640x480"

The advantage of this is that your monitor doesn't have to be in one of 
the compatible TV modes: 1024x768, 800x600, 640x480, and your workspace 
is unaffected by the TV out.

To use the TV, just send any X window to the second screen of the 
primary display:

mplayer -display localhost:0.1 -vo xv -fs Foo.avi


I even got this working with the MythTV client.  Now (well, after i get 
LIRC working properly) my g/f can watch downloaded TV episodes while i 
do "work" on the computer.

Good luck,
Mike
