Well, hey, you missed my point (and I'm pretty sure you missed his,
too--as he seemed to want something that works with a "stock MythTV
build" (quoted from his post)). My solution works with any version of

Where did I say, "shut down mythbackend?" I said, "tell Myth not to use
it [the card] by not configuring it [the card] in mythtv-setup." That
means he should configure all his other cards in Myth, and--to be
complete--run mythbackend. Therefore, he would have one card dedicated
to radio and all other cards available for TV.

What, not running MythTV means that MythTV won't record things? I never
would have guessed.

Which means as new shows "cascade" into those recording slots (from
previous conflicts), you'd have to insert more overrides.

Yep. Definitely not a workable solution.

Extending the EXECTV's support for marking a capture card as unavailable
would be an easier solution if you planned to write new code. I think
it's pretty much as easy as sending a "FREE_TUNER" command to the backend.
