Where did you find them? I found datasheets for the 24108/24110 but
not for the HM1811/1211.

Sure, we can just put it into its own directory in the new DVB
driver framework (DVB NEWSTRUCT branch), e.g. DVB/driver/pctv (or
conexant, hm1xxx, whatever ?). 
AFAIK the Pinnacle PCTV should deliver the complete TS? 
All you have to do then to support the complete API including filters and
networking is to register with the other dvb modules (dvbdev,
dvb_demux) and feed the TS to them like the Nova card part of the 
Siemens driver does.
The frontend driver should go into DVB/driver/frontends.
