Is this something to do with input groups? - this is something I have failed to get my head around and just allowed mythtv-setup to specify it in its own mysterious way :)

For each tuner the first input group is set to something like /dvb/adapterN/frontend0 and the second is set to 'Generic'. But as I understand it, to permit 4 simultaneous recordings (assuming appropriate choices of channles/multiplexes) the second one should also be unique. Is this wrong?

OK so I have two entries in input connections, one for each physical tuner. But under each entry there are settings for 'Input Group1' and 'Input Group 2'. I'm confused as to what the second input group is for.

Is there anything to enabling multi rec other than setting 'Max recordings' to 2 under 'Recording Settings' for the card in the backend setup? (2 appears to be the default).

Thanks,

Mark
