Getting back to your original question.

As I understand it,  ABC news is on 5 channels so MythTV records 4 
copies of it, and then fails to record another program because it ran 
out of tuners (conflict).

If you use schedules direct for the guide, schedules direct assigns a 
unique id to every program so that this does not happen. MythTV 
recognizes the extra showings as duplicates and only records one of 
them.  I don't know about Schedules direct in Australia, whether it is 
available or whether it assigns unique ids to shows. Schedules direct 
does offer a 7 day free trial and a monthly option that you could use to 
try it out. It is a bit of a pain to set up.

I assume you are using EPG for the program schedule. Can you set a 
filter of "this channel" in your recording rule? You must know which 
channel carries a program. Surely they don't switch channels around on a 
daily basis?

Another thing you could do is give a higher priority to the recording 
rule for program B. Then when 5 channels show program A and one shows 
program B, then program B will be recorded along with three copies of 
program A. At least you will not miss program B.

Record One showing only or only this showing are not helpful, that means 
one showing only, ever. You would have to set it up again every day.

Some of the filters may help. Perhaps "First Showing" may help. Even if 
4 showings are at the same time, MythTV may decide one of them is a 
first showing. I have not used this so I may be wrong here.

Power search allows you to set your own SQL, so if  there is something 
unique about the subtitle or description that identifies which show you 
want, you could create a power rule that restricts it to the one you want.

A lot of options to try. You can set up different ways then look at 
Upcoming recordings to see what will be the result.

Note: If you are running a recent version of master (pre-34) you can use 
the web app to set up and modify recording rules. Preferably don't use 
mythweb, it is out of date and has not been maintained.
