I've seen this 100% issue happening when using Xv and that screen rate
match exactly the framerate ; you then see X using 100% of the CPU
time ; that's a nvidia bugs supposed to be helped with "UseEvents"
"True", in the device configuration.
This didn't work for me however and I fixed it using OpenGL renderer
instead of Xv.

You didn't state BTW what's using 100% of the CPU time, I would assume it's X.

However, why don't you use VDPAU on your system (it supports it)? IMO,
the VDPAU deinterlacers (Advanced or Temportal) gives much better
result than even Yadif.
