Yes multi-rec is fine, in that one tuner will record 3 channels from the  
same mux simultaneously. I did try that PID filter option but it prevented  
the tuners from working at all so I removed it and can live with the 1 Hz  
log messages. I haven't investigated further - I don't fully understand  
PID filters - so might have another go when I find time. Maybe it needs a  
cold start or something.
FWIW I couldn't get a usable firmware following the wiki method either.  
But google found one that worked easily enough. Again I don't understand  
the difference between Windows/Linux firmwares so haven't commented on the  
wiki yet.
