Everything that I've heard indicates that nVidia simply doesn't do
interlaced output correctly.  You get some weird tearing or other
problems because the output frequency isn't right.  Earlier drivers had
much worse problems.  If, however, you have a FX5200 card (AGP), and you
don't mind being unable to upgrade past kernel 2.6.22.xx and
xorg-server-1.3, then you can run the 8774 nVidia drivers, and
everything works perfectly.

But my TV is interlaced, so any deinterlacing will just make the picture
worse (not to mention that my AMD 2500+ will run out of CPU if I

Are there any cards that work with current drivers to do interlaced
output?  I'm thinking of upgrading my system, and it seems that nVidia
is out.
