Dish fed locals and OTA locals showing "off air" in guide

[jlhugh]

i got 1 channel that has been doing this and it is a channel that has had some problems, but it has been fixed for a few days now. if you look ahead in the guide about 3 hours the programming starts showing up. as that time approaches it turns to off air. i chatted with a tech but i need to be in front of the tv so i will wait until i get home. i was just wondering if anyone else has seen this and it if is fixable on my end, or the station or dish needs to fix it.
