subclassing dtvSignalMonitor 
  ideally would have only needed SignalMonitor::Init to change
  but it also needed scanwizard/siscan to handle it as well
    -  GetDVBSignalMonitor()->UpdateFiltersFromStreamData(); 
     was where I stumbled - it just felt wrong to change all this lot
 
subclassing dvbsignalmonitor 
  - I was hoping that I would only have to implement            
AddPIDfilter/RemovePIDFilter/RunTableMonitor 
 - however this needs much of the private to become protected
  in addition to the SignalMonitor/SiScan amendments above
  
I was thinking it should be the other way round - ie the base 
dvbsignalmonitor class actually being the 'usb' version - not supporting 
PES_OTHER/TS_OUT and the current dvbsignalmonitor class extending that by 
adding PES_OTHER/TS_OUT support - Again its a lot of change so I thought 
I'd see if the big wide world could see an 'obvious' solution - on the 
basis that if you show something that works its easier for someone else to 
spot the best way to do it properly!

good (for now :)  )

thanks again!
