I recently installed OTA tuners for both of my Hoppers and within 24 hours the sub-channel EPG information appeared, but not all. For example, my local ABC, CBS and NBC each have one sub-channel and the EPG shows individual program listings for Movies, Antenna TV and This TV, respectively. Which is very convenient. However, my local Fox station has two sub-channels, RTV and Grit. Oddly, only RTV shows EPG information. Grit, OTOH, just says, "Grit" across the entire EPG. Independent channel MyTV has one sub-channel, METV, and like Grit, just says, "METV" across the guide. Any idea why the Fox station would have individual listings for RTV, but not Grit? And, why MyTV would have no listings at all for METV?
