I tried using this format « http://nitro.ltd:25461/xmltv.php?username=xxxxxx&password=xxxxx» but its not working on my nvidia shield tv. If i try it on my iphone with that link, it works.

I think the iptv smarters pro on android needs in another format?

Use xtream codes api mode

So if you're not receiving epg guide but you have one, how do you add it in manually?

The picture above shows "edit epg" how do i get that screen?
