EPG Data with Wrong Channel--Fixable?

[scm]

Problem:
I am in the Birmingham, AL area. We, as most, have two OTA PBS digital feeds. WBIQDT (RF 53) is the HD feed with unique programming and WBIQDT2 (RF 53.2?) is the SD feed retransmitting the analog programming. Zap2It recognizes WBIQDT in the EPG, and lists its programs, but when Sage attempts to tune the station, it tunes WBIQDT2 instead. If I use the add channel function and add WBIQDT2 and give a channel number as 53.2, I can tune the HD programming, but I don't have any EPG data.

Question:
Is there a way in the Sage Properties file to either change the frequency Sage is incorrectly tuning for WBIQDT or a way to associate the EPG data with the channel I created?

Anyone have an answer, or is this impossible?
