I also use bttv cards and I sometimes found that [metro] and [fps] don't 
agree even when the CPU usage is less than 100%. It varied in irregular, 
hard-to-predict ways. I mean, for each [metro] rate, it's stable (except 
for Ruby's garbage collection), but sometimes lowering the [metro] rate 
makes the framerate slower instead of faster. I haven't seen that in the 
last two years though.
