This makes sense; I'm getting clear QAM channels from my cable company, 
so the HDHR picks them up as the "real" channels (134.0, 135.13, etc.) 
but the listings data are all mapped to what the OTA channels are (2-1, 
4-11, etc.) Maybe I'll try setting an antenna up on the HDHR's second 
tuner, just to see what happens when it does its channel scan.
