Sounds like you have OTA enabled. Do you have an OTA antenna connected? That's the only way you'll get the XX-X channels.max1 said:
The channels in your guide that have call letters listed are the DirecTV MPEG4 HD channels.
In my market, I see
SA3 (KCRA NBC SD - delivered by DirrecTV)
KCRA (KCRA NBC HD - delivered by DirrecTV)
3-1 (KCRA OTA - from the antenna I have connected to the OTA port).
If you see something to the affect, you should be able to disable OTA and just have 2 channel 7's instead of 3. Make sense?
