Looks the same as my circuit:

The solution works very well, except I hit a problem with the nvidia 
drivers (something that I have reported to nvidia and have had no response 
- - maybe the people using plasma screens with VGA inputs can confirm if 
this is also a problem for them):  When running the VGA output of my 
Nvidia MX440 in interlaced mode, all video/graphics output through XV got 
halved in resolution.  i.e. the video was physically the right size, but 
it had half the number of pixels it should have had (vertically at least), 
leaving it rather blocky.  The even more odd thing was that it wasn't just 
making sure both fields are the same - if I feed it a 100 pixel high 
video, resized to full screen it only renders it with a resolution of 50 
pixels high (resized to full screen).

So since nVidia haven't bothered to acknowledge or fix the bug, I'm back 
to using the svideo output of the card for now, which isn't quite as 
sharp.
