Nothing on your device records. The channel is captured on the provider's servers as it airs and kept as segments for a set number of days. When you scroll back in the guide and press play, your player does arithmetic: it reads the program's start time and duration from the EPG, builds a timestamped request and asks the server for that window. Panels expect different shapes for that request. Some want a UTC timestamp appended to the live address, some hand back a fresh address from an API call, and the playlist is what tells the player which to use. If the guide entry has no precise start time, the player has nothing to calculate from and the replay quietly fails.

1. 1Recording happens upstream, so your storage is never touched
2. 2The EPG supplies the timestamps the request is built from
3. 3A guide with rounded blocks instead of real start times breaks replay

Replay is enabled per channel, and in practice per channel group, because the archive is created upstream of the service you buy from. A group ingested from a source with an archive gets replay; a group ingested without one does not, and no setting on your end changes that. This is why a service can accurately say it supports IPTV catch up while the specific channel you want has none. It also explains the most common question in this area: one channel replays fine, the one beside it shows dead entries when you scroll back. Judge a catalog by testing three groups from different regions, not the first channel you open.

Support is narrower than most pages admit. TiviMate and OTT Navigator read the playlist attributes and build the archive request properly. IPTV Smarters exposes replay where the panel provides it. Kodi manages it through the IPTV Simple client, though the archive mode usually has to be set by hand. VLC cannot do it at all — it plays a URL and has no guide layer to calculate a timestamp from. So if replay is missing, load the same account in a second player before deciding the service is at fault. An account that shows nothing in one app and a full week of archive in another has an app problem, and that fix costs nothing.

1. 1TiviMate, OTT Navigator: full attribute support
2. 2Kodi via IPTV Simple: works, usually needs manual setup
3. 3VLC: plays streams, cannot request an archive window

Give it twenty minutes rather than a week. Open the guide, scroll back to a program that finished yesterday and press play, then repeat on three groups from different regions. Note how far back the guide will scroll and still play — that number is the real window, whatever a feature list claims. Start a replay and jump forward inside it, because seeking inside an archive stream is where weak setups stall. Run the same test on a second device on the same account. Our $5 24-hour trial exists so you can run all of that yourself instead of taking a claim on faith, and plans add a 7-day money-back window.

It is a rolling window, not a personal library. Once a program falls out of the window it is gone and there is no way to pin it. You cannot keep a copy on the device, you cannot pass it to anyone, and archive access ends when a subscription ends, because the recording lived on a server and was never yours. Some titles carry upstream restrictions and stay excluded even inside the window. Treat replay as a second chance at last night's programming rather than storage. One more limit is worth naming: whatever was not recorded because the source was down cannot be replayed, which is why an uptime figure matters here.
