I live in a town where the local broadcasters, for reasons unknown, "swapped transmitters" such that the channel that describes itself as "5" broadcasts as OTA "9.1", and channel "9" broadcasts as "5.1". I was hoping that by renaming the OTA station to the satellite channel it corresponds to, the Dish guide would follow, but it does not. Is there anything I can do with the OTA software to reflect these changes, or is it something only Dish can do? The broadcaster told me that they made this switch in the fall of 2009, and "all providers wee notified"; it doesn't sound like this swap was temporary; both stations are owned by the same company and their broadcast equipment is co-located.

Did you try rescanning for OTA channels? That might clear it up.

DISH uses the "TSID" that each channel broadcasts along with their signal to match a received signal (regardless of RF channel the signal is received on) to the EPG data they carry on satellite. If the TSID broadcast by the station does not match the one DISH is using for the match the EPG will not be correct.

The San Fransisco channels in question and the channel used for EPG on a DISH receiver are:
5-01 KPIX TSID 0x017B, Subchannel 01 (DISH Channel 6439/8221)
9-01 KQED TSID 0x017F, Subchannel 01 (DISH Channel 6448/8226)
9-02 KQED2 TSID 0x017F, Subchannel 02 (DISH Channel 14016)
9-03 KQED3 TSID 0x017F, Subchannel 03 (DISH Channel 14017)
9-04 KQED4 TSID 0x017F, Subchannel 04 (DISH Channel 14018)

I wouldn't worried about the "swap" - each channel has own call sign (and unique number [TSID] for each station's mux);
it would be easy remember by call-sign instead of three numbers: RF channel, digital channel, virtual channel number
