[FONT=&quot]Hi everyone...[/FONT]
[FONT=&quot]
I have the following problem: I installed the app "smart iptv" on my amazon fire tv stick und uploaded a iptv-playlist. When i wanted to open a video from that playlist, i was asked if i want to open the video "always" or "just once" with the suggested video players.

I choosed "always" and selected "kodi" as a external player.

Now i have the problem, that i can't make this configuration undo. All videos open with kodi all the time....

I really need your helps.......

Thank you very much
