My new MythTV box will have a pcHDTV 5500 for HD recording and a Hauppauge 250 for standard TV. Getting the programming information working for both so they didn’t stomp on each other was a challenge. The fix is to simply define two inputs of Zap2It. They’re both configured identically, but have different names. I then loaded the channels from my channels.conf (described later) for the HD side of the house, then scanned regular TV channels and everything fell into place.
