Which is **VERY** different to selecting tuners in your recording rules and isn't related to the OPs problem. As Mike points out, there are simpler ways around the issue. All I can say is that I've never observed a conflict caused by the scheduler using both of my physical tuners for the same mux (we have 5 muxes available here*, and I have 2 physical tuners).
* Being pedantic, there is a 6th, but that's using DVB-T2 and I don't have a tuner for it, and nor can my frontend manage HD playback.
When the OP comes back with the missing information, then someone will be in a position to offer advice.
