The femon plugin gets this information directly from the video elementary 
stream. So the problem remains to get that high bandwidth stream from the 
FF-card. May be a solution would be to request a single PES paket with the 
PES_OTHER flag instead of PES_VIDEO so that it won't get routed through mpeg 
decoder. This would slow down the tuning process though.
