I took the plunge and renamed the channels from the main channels list in setup by clicking twice on each one. I saved my config before I did the renaming but it did not save me and the program guide is not updating again. Tried deleting all ch's and load the working config and just reloading without. Same result I have all my ch's and they work just no schedules direct info.No. Once the channels are linked, they stay linked even after renaming.
