channel guide

[dempsey_dog]

I have 2 HD receivers. I also have an HD OTA antenna on both that use to get my locals. ON both of them, the OTA locals show up in my receiver's channel guide. However, on 1 the channel guide is updated and current for all OTA channels. On the other, all but the local FOX affiliate are current. For FOX, it does not show the shos, it just says "digital programming" or something of the sort ( I am not home).

Does anybody know why it works on one, but not the other?

Thanks
