If you have a remap line of say:
11-1 2 qam256:507000000 1

You can specify the device/tuner by adding it to the beginning of the line:

XXXXXXXX-0 11-1 2 qam256:507000000 1

XXXXXXXX would be the Device ID. the above example tells the driver that that channel is only available on tuner 0. You can then set tuner 1's channel 2 to a separate channel.

XXXXXXXX-0 11-1 2 qam256:507000000 1
XXXXXXXX-1 41-1 2 qam256:561000000 3

Of course, you will have to make your lineups accordingly.

The remap utility does not yet have the ability to do this but it will be in the next version.
