Wally is the same way, so it is not just a ViP thing.Chalk another one up to ViP? I've always had guide data on Flex without locals.
Even the newly-added PBS subchannels (PBS Kids) do not have guide data in my area, so it looks like Dish has even stopped adding new subchannel guide data for PBS stations.I doubt it. Most of my subchannels do not have guide data, with the exception of MeTV, AntennaTV and PBS. It seems if the subchannel isn't grouped with a major big 4 network (or PBS), then the chance of guide data is slim to none. Even on a major network, it's still a crapshoot.
I kept local guide data on two deactivated ViP722k's that I was still using for OTA, so you should be fine.If someone can confirm dropping locals and having data guide on a 722k. I would drop locals in a minute.
