Quick answer

On Apple TV, download a tvOS player such as IPTVX or UHF from the App Store, open it, and add your Marinios IPTV account using the Xtream Codes details or the M3U link from your activation email.

Apple TV 4K and Apple TV HD (tvOS) offer a smooth, polished viewing experience. Several high-quality IPTV players are available directly in the App Store, so no workarounds are needed.

Some tvOS players offer a free tier with optional in-app purchases from the developer. Your Marinios IPTV subscription is separate from any app purchase.

What you need before you start

Apple TV 4K or Apple TV HD with the latest tvOS update.
An Apple Account signed in on the Apple TV.
Your Marinios IPTV activation email.

Supported login methods on Apple TV: Xtream Codes API, M3U playlist URL. What's the difference?

Recommended player apps for Apple TV

Polished Apple-native player with Xtream and M3U support.

Install a player from the App Store

Steps

Open the App Store on your Apple TV.
Select Search and type IPTVX or UHF.
Select Get and confirm the download.
Open the app from the home screen.

Sign in and load your Marinios IPTV playlist

Use the details from your activation email. Copy and paste where you can, and keep these details private.

Open the app and choose "Add user", "Add playlist" or "Login with Xtream Codes API" (wording varies by version).
Enter any name you like, for example Marinios.
Enter the username, password and server URL exactly as they appear in your activation email, including http:// or https:// and any port number.
Select Add or Login and wait while live channels, movies and series load. The first load can take a minute or two on slower devices.

In the app, choose the option to add a playlist from a URL (sometimes called "M3U URL" or "Load playlist from URL").
Paste the full M3U link from your activation email. Avoid typing it by hand where you can, because a single wrong character breaks the link.
If the app asks for an EPG or XMLTV URL, paste the EPG link from your activation email.
Save and let the playlist download. Large playlists can take longer to load on older devices.

Set up the TV guide (EPG)

Xtream Codes logins import the guide automatically in most tvOS players. For M3U, add the XMLTV link in the app's EPG or Sources settings.

Common Apple TV errors and fixes

Typing long URLs with the Siri Remote: Use the Apple TV Remote on your iPhone to type or paste the details, or use the app's QR/web import option if it offers one.
Video stutters on Wi-Fi: Connect Ethernet (Apple TV 4K) or move the router closer, then restart the Apple TV.
