Recording iptv

i suscribe at one iptv abonnement.
I use iptv simple client to see my different channels (with an M3U file).
I see on the menu of iptv simple client we can records the tv.
How can I do? I try to connect my external hard disk, but it’s doesn’t works…

I’m currently able to record my IPTV streams within emby. I set up Emby with all my local media – tv shows and movies, then added my paid IPTV m3u playlist and some schedules direct guide data. Voila, live TV, EPG, and recording. I can even schedule a whole series to record, just like you would with a standard STB DVR.
