The drivers work fine. I am not aware of any problems. All Digital Devices cards and tuner variants are supported by the driver http://linuxtv.org/hg/~endriss/media_build_experimental ddbridge (Lattice bridge): - Octopus (all variants) - cineS2 v6 - DuoFlex S2 (stv0900 + stv6110 + lnbp21) - DuoFlex C/T (Micronas DRXK + NXP TDA18271C2) ngene bridge: - cineS2 (v4,v5), Satix S2 Dual - PCIe bridge, mini PCIe bridge - DuoFlex S2 (stv0900 + stv6110 + lnbp21) - DuoFlex C/T (Micronas DRXK + NXP TDA18271C2) For a German description, see http://www.vdr-portal.de/board16-video-disk-recorder/board85-hdtv-dvb-s2/105803-aktuelle-treiber-für-octopus-ddbridge-cines2-ngene-ddbridge-duoflex-s2-duoflex-ct-sowie-tt-s2-6400 >From an operational point of view, the driver is ready for the kernel.

Yes, this could be done: ++ The CI could be used with any application. -- The CI will be attached to one tuner exclusively. It is not very hard to implement this.
