The German (channel site = "web.magentatv.de" or "tvtv.ch") and Spanish (channel site = "movistarplus.es") DAZN 1 and DAZN 2 programs have different content, different site_id BUT the same channel name. Other sources are not correct.
It would be good if one of those sources had HD or something like that in the sequel, so Dazn 1 or Dazn1 HD or..., and the other one remained unchanged.
By the way, there are no sources at all for Italian DAZN.
