Ah, yeah, when you change non-rule priorities, you're telling Myth to do
things you may not want it to do.

Exactly. IMHO, you should /never/ change any priorities other than
recording rule priorities unless you've read and you understand all of
section 12 of the HOWTO.

As a matter of fact, this exact idea is covered in detail in that section.
People generally change channel and input priorities thinking they're
affecting which channel or which input is preferred, but they're
actually affecting which shows are recorded.
