The order in which inputs are chosen for Live TV or recordings is 
determined by the Live TV and Schedule Order of inputs.  This should be 
used to indicate which channel (or, specifically, which input that 
receives that channel) is chosen for Live TV.

If you change the priority of a channel (or input)--in current MythTV 
(this used to work differently before 0.27)--then once MythTV has 
decided to record a show that appears on multiple channels, it will 
prefer (but not guarantee) to record that show from the higher-priority 
channel, even if it's not the first-schedule-ordered input.  You can use 
this, for example, to prefer recording from a channel on a lower-quality 
input if you have particular problems with that specific channel on your 
higher-quality (first-schedule-ordered) input.  So, it allows an 
override of the schedule order to an extent, for specific channel(s).  
However, you should always set the schedule order to use inputs in the 
desired order and only use channel priority for overriding that order 
for problem channels or similar.

If you're in Live TV and request some channel that's available on the 
current input, it will change to that channel.  If the channel is only 
available on another input(s) (not the current input), but the next 
input in Live TV order that can tune that channel is in use for 
recording (i.e. potentially because you changed the priority of the 
channel), you'll get an error that the input is busy and will have to 
manually switch to another not-in-use input that has the desired channel 
available to change to that channel.  Priority won't affect decision of 
what input (nor which channel) to use for Live TV.
