Prepare a supported device
The developer lists Samsung, LG, VIDAA, Android TV, Google TV and Fire TV. Check current compatibility in the store on your device. Menus and remote behaviour may differ between platforms. Confirm internet access and the device clock first, since incorrect time settings can also confuse programme listings.
Add the content source
Duplecast states M3U/M3U8 and Xtream support. Fill the fields for your selected method: the complete URL for M3U, or server and account credentials for Xtream. Save KAPTAN IPTV as the name, load the list and test one channel. Do not put your IPTV password into a licence screen; those fields serve a different purpose.
Licence activation with Device ID and Device Key
The developer describes the licence information under Settings → License. Use Device ID and Device Key only in Duplecast’s official activation flow. Check the current payment and licence terms first. Activating the player does not renew your channel subscription. Refresh the app after activation and separately confirm that your content account is still active.
FAQ
Is the Device Key my IPTV password?
No. The device key and content account password are different.
Is the licence page also the playlist screen?
No. Content setup and licensing are separate flows.
