Keep in mind that this app is configured for a demo IPTV portal for testing purposes. If you want to use the app you have to configure the app for your IPTV provider.
The app doesn’t support m3u (or any others) playlists.
NOTE: This app is designed to be used by experienced users. To work correctly it must be configured first and if you’ve never configured IPTV boxes it may be difficult for you to configuring it. Keep in mind, that this app contains a lot of settings that has to be configured before it may be used by a user(read wiki first). If you do something wrong you may make the app unable to work.
