Ahhhhhh easier to just use a Firestick
Another option (although you'll probably run into compatibility issues again) is casting from a browser. Chrome browsers on PC or phone etc I think will let you cast to another chromecast on the network. That way you'd log in play etc on your PC and cast the fullscreen video to your tv, I've not tried myself but it may work
Get a firestick, its the way to go. i use one here in central europe no issues, UI is decent and if you dont like it you can change it
Iptv does , if I use ifollow always at the pc, so can’t comment iptv is there if I’m in bed or out of the house.Does iFollow work on the firestick?
