Well, I did this recently.  It took quite a bit of research, but the
xorg.conf below works on my Dell 8600.  It has a TV-out plug and it
came with a dongle that has 3 plugs at the other end: S-video, composite
and S/PDIF digital audio.  I'm using the center one (composite) plugged
into the front of the VCR, but it could go into the back of the TV too.

I found a similar xorg.conf on the internet and extracted the relevant
parts and added them to the standard xorg.conf that lenny had generated
for my display (WUXGA).  Plugged in the cable into the VCR input and
after selecting the right input on the vcr, I had a blank desktop on
the tv.  Now, the next step - displaying video on the tv from applications
run on the main display took some trial and error.  It turns out that 
you need to use -display :0.1.  Once I had figured that out everything
worked.  The TV display is actually a full display and I can move the
mouse to it and activate menus and so on.  Of course that's pretty
useless since the low resolution of the TV makes all text unreadable,
but if you had a hi-def tv it would be useable that way.

Here's the xorg.conf:
