  The problem you are encountering, is that you've mixed two different setups.  
You can use the card you have as one card, with two independent screens.  
That will show two independant desktops.  Or you can set it up, as TwinView, 
which creates either one virtual desktop that stretches over two screens, or 
clones the original display on the second.

  In your case, cloning and stuff is quite hard since you are using a 
1280x1024 on the primary screen, and 640x480 on your TV.  So, a virtual 
desktop with twin view must be what you are striving for (I'm guessing).  If 
that's the case, the extra Monitor section, and the extra Screen section for 
the TV aren't necessary.  For a twin view setup, you specify the following 
extra options instead of the Screen, Monitor sections for the TV.

Option "SecondMonitorHorizSync"     "30-50"
Option "SecondMonitorVertRefresh"   "60"
Option "MetaModes"                  "1280x1024; 640x480"

  For reference, see Appendix I in the NVidia README file.

  If your intention was to setup an extra X screen, that shows a desktop 
independant of the one on the primary screen.  You cannot do that, with the 
TwinView option.  The NVidia briefly mentions this, but doesn't go into any 
detail on how to do it.  Iff, that is what you are trying to do ... you need 
to comment the TwinView option and its associated options, and create a 
different Device section for the TV, which you then combine in the Server 
setup section, of your XF86Config file.
