The streams come from arconaitv.me but the .m3u8 stream file changes every few hours so you would have to keep updating it.
Would love to see Mobdro integrated in Live Channels though. It would be fantastic!
I wish!
I emailed Mobdro early January about ATV and got this reply.
"Mobdro will only work on android devices, but not in an android TV, sorry"
I guess the "easiest" way would be to somehow find the stream url's and hope they dont have tokens or anything so you can put them into tvheadend or cumulus
If you could some how capture the link to the stream then maybe use cumulus TV to create a channel?
