It's channel 270, Planet Green HD on Wide Open West in Michigan. Like
I said, the channel works fine as long it's either not streamed from
the backend, or it's not the starting channel for live tv. So at least
the PAT and PMT are there and working. Don't know about any of those
other 3 letter acronyms (though I hope the CIA isn't keeping tabs on
what I'm watching)
