Hmmm...

I was using 0.18.1 compiled *with* OpenGL support, which caused me  
trouble with nVidia's 1.0.8178 drivers. Commenting out "load glx" (as  
well as "load dri", suggested by the nVidia docs) did indeed solve my  
problem. This was with a 5700 card. My CPU load is now below 5% when  
watching TV and it looks good (well, for consumer grade encoding that  
is).

It doesn't seem that the nVidia drivers are loading GLX.
