As has been indicated several hundred times before on the mailing list, 
the IRC channel, and elsewhere on the internet, the decoders run in 
dedicated hardware, while the deinterlacers run on the shaders.  They 
all have the same decode feature set, but the low end cards just don't 
have the performance for the most intensive deinterlace filters.
