Live TV and provider VOD come from an IPTV subscription you already have. MIRA talks Xtream Codes and M3U / M3U8. Pair it with a debrid account so movies do not live only in a 4,000-channel catalogue.
From your IPTV provider, copy either Xtream Codes (server URL, username, password) or a full M3U / M3U8 playlist URL. XMLTV EPG, if they give you a separate guide URL, is optional.
On a phone or computer, open miraplayer.tv/account → Sources → IPTV.
Paste the credentials or playlist URL. Click Test, then Save. Do this on the website so you never type a password with a TV remote.
Open MIRA on the TV or at miraplayer.tv/app. Live TV and the guide fill from that provider. Movies still prefer your debrid when both are connected.
Also: Stremio add-ons, Jackett, or the full list under Connect your sources.
