Some of my channels (specifically discovery channel) do not have an EPG available in channels. Can we request it be added?
EPG sometimes does not map correctly and has to be set manually for a given channel.
Go to Settings -> Sources -> Select the source from where you get Discovery.
Then -> Manage Lineup
Scroll down to Discovery
Click on the symbol on the far right (edit or 'X')
Drop down the setting next to the search box and "Search All Lineups"
Then type in 'Discovery' (without quotes)
See if you can find something that works for you.
For me it is 'DSCHD'
You may just try typing in DSCHD.
When you close the window, you should see it redownloading the guide data. If not force a relaod.
I think it's the code DSCHD we did not have. Will look for that one.
