you can make an m3u of sling channels to play in any m3u program, you just need to code it correctly, the add on is what autenticates the stream, not simple iptv player, I can help if you need  

That would be amazing!  I wasn't sure if there was something with Widevine that prevented that...  I swear I got tv mosaic to play a single stream the other day when I tested and then after that initial test it stopped working.

What I did was use the web server this addon spins up as the URL for the remote M3U and XMLTV guide URLs in TV Mosaic.  There's really not much more to it than that (at least from passing in a M3U and XMLTV guide)...  It does find the channels as well as the guide info using that but the playback appears to time out...  

If we need to take this out of the scope of this thread please let me know, I don't want to derail the thread.  I figure this would be the same setup to use for any of the other PVR backends though...  so it *might* be relevent 

drop me a dm if needed, keep post clean

I am unable to DM, I'd be very, very interested. I've lost almost a week trying to figure it out.
