I'm still unclear on what to do here. The two channels (A and B) ARE
labeled differently. They have different channel numbers and I used
different channel icons too. If I edit the call sign of channel B to be
different, then it won't record at all, because MythTV records by call
sign, which will no longer match the PSIP call sign value from the
broadcaster. I think there needs to be a way to just tell MythTV to
record "this channel" and it does.
