I just setup the joagomez container, on my test system, and it exposes all the various regions into separate urls. Though, there are 3 versions of each. I assume the "maddox compatibility" url is the one to use for Channels?
The ALL maxes out a 750 channels i think it was, so many that it heavily lagged the web browser tyring to load the guide for it.
I did have a quick look at the other regions playlists. I notice that some have more channels.
Like CA has 6 South Park specific channels, a dedicated Star Trek TOS and TNG channels, Nicktoons, Comedy Central Standup, Arthur, and a few other specific channels that are not in any of the US playlists.
UK, also has a few extra ones.
Both have many of the same named channels, though most are airing different episodes or programs than the USA version.
The UK and CA both have Arthur channel, but each is airing different episodes.
So, i guess, if one wanted to add a some more content to their TV options, u could add the extra regions playlist/s as a additional custom channel source. Either some different channels, or the same, but just have different episodes on...gotta watch out for channel numbers though.
Edit: Seems the 2 extra Star Trek channels, just repeat the same dozen or so episodes, all the time. Weird.
What i can't figure out, is what is this containers equivalent to default US region output of the maddox or nocords solutions? This container has both US East, and US West, and Local.
