As cable companies drop clear channels it usually fails. My old DVRs have lost those guides. Seems a shame that those DVRs are less than 5 years old and the cable co dropped the TV Guide channel that it used.
Sorry but I can't know the technical method this LG used but it can be broken by folks other than LG.
I have a new HR929T 3D Blu Ray player/PVR and have found that with the electronic TV Guide only appears for the channel selected. If i choose a different channel, the listing will be added to the existing one being shown.
Has anyone else came across this? I am in the Newcastle region if that helps.
