And of course after spending a few hours this afternoon and definitely after sending my message to the list, I think I’ve found part of the problem. 

I finally remembered the TBS6909 has 4 aerial inputs and requires creating a modprobe conf file to set the card to use the single aerial input #3 across all the tuners. Without the lower number adapters I tried with dvbtune and dvbstream, effectively had no aerial attached.  Recreating /etc/modprobe.d/mxl58x.conf (and rebooting) since it went missing somewhere between the big upgrade, removing and reinstalling the TBS drivers, and now dvbtune is working with that card:


me$ dvbtune -f 1219000 -s 22500 -p H -tone 0 -c 2
Using DVB card "TurboSight TBS 6909 DVB-S/S2 "

Should be smooth sailing from this point…. 8)

Thanks Stephen, previous conversations are coming back to me now - shall dig through archives and look at the numbering patch for the card.
