I've installed a new USB tuner and in TV Server config, disabled the old dual tuner and put the new dual tuner at priority 6 and 5.
Then under TV Mapping I've mapped all the channels to both tuners and I can see BBC One is in the list.
If I go to Manual Control and try to start timeshifting on BBC One, it says "all cards are busy". It's actually grabbing the EPG from BBC One at the moment, so it can obviously tune to it. I tested a number of other channels which all work fine. I tested in MP as well and for BBC One it says "no free card available" but the other channels work.
