I've got a Sling TV Blue subscription entered as a source in my Channels DVR setup....
Right now, in the Sling app itself just via the internet (w/ no antenna), I get the local channels for ABC, NBC and Fox (because I'm in one of the select large metro market areas), the NFL Network, and a ton of other various cable and free stream channels.
However, within my Channels DVR setup, I get very little from Sling via TVE: My Fox local channel, nothing from my ABC or NBC locals, no NFL Network. Used to get USA Network, but it's now gone.
But I do get these other channels via Sling TVE in Channels DVR: FX, A&E, History, Lifetime, Nat Geo, and Fox News.
Along with a long list of lesser known channels that, if I understand right, are sourced from Channels DVR to me because I'm subscribed here and have a pay TV account?
