Well, in the event your listings don't provide the right information, 
you'll have to use a hack.

However, a "this channel" rule will only allow you to record from one of 
the 2 channels.  That means you'd either have to make 2 "this channel" 
rules (which would be about as ugly a hack as you could get--since 
they're otherwise identical) or use something else--i.e. in this case, 
I'd recommend a custom rule that specifies which channels (or channel 
group) to use, or which to exclude.

Channel priorities wouldn't be ideal because they'd affect how every 
show that airs on the channel compares to other shows on other channels, 
and could cause you to miss shows you want while recording shows you 
care less about.  (Well, that's true until 0.27(? I think it's going to 
be in the next version), when channel priorities become what users 
actually think they are.)
