The nVidia cards do support interlaced modes - there is a hack for the 
opensource driver that lets you set them.  Unfortunately the opensource 
driver is slow, doesn't provide the /dev/nvidia0 device, and the closed 
source drivers don't support interlacing (and are closed so we can't add 
support ourselves).  Unfortunately I can't see nVidia bothering to add 
interlace support because there is almost no demand for it (even though 
AFAIK all they need to do is set a bit in a register).

Unfortunately on a non-NV card you can't do vsync, so tearing is a problem 
and you have to deinterlace the video otherwise the field order is often 
wrong.

How much CPU does your X use up when playing video BTW?
