I would assume it is getting that information via the MythTV protocol.

But it wouldn't surprise me to learn that the live TV code assumes that 
the back-end consists of one or more tuners that all receive the same 
set of channels. Thus tuner switching and channel switching are handled 
by two independent operations (with a menu for each).

That would clearly break in a scenario like yours where certain channels 
are available only on specific tuners.

As I understand it, generating the TV listings is the *only* thing the 
direct database connection is used for by the live TV feature.

You might want to repost that query on the developer's list.
