I don't think you can get enough bandwidth with bt878 cards to run 20 
FPS for all 4 channels.  (I could be wrong, but PCI + CPU just has so 
much bandwidth.  I tried to do something similar at one time but gave up 
because of the CPU and hardware requirements.)

If you have enough slots, you can get 4 x Hauppage PVR150 cards for less 
than $200 if you shop around; these provide a compressed mpeg2 stream at 
30 fps with no problem - and no CPU load.  Check out the ivtv project 
for other supported hardware.  (Warning, though - it seems that Hauppage 
has started shipping an unsupported card in PVR150 boxes...)

I'm not sure of the status of hardware compression support in the v4l 
project...
