IPTV catch-up (replay) on LG TVs

Updated 12 November 2026 · Gridline

IPTV catch-up, also called replay or timeshift, lets you watch programmes that already aired, usually up to 7 days back. The recordings are kept by your IPTV provider, not by the TV, so it only works with providers and channels that offer it. On an LG TV, a player that supports catch-up plays it from the TV guide.

How catch-up works

Your provider records its channels on its own servers for a number of days. A player that supports catch-up asks the provider for a programme at a given time and plays it like a recording. The TV does not record anything.

How to tell if your provider has it

How to use it in Gridline

  1. Go back in the guide. Press ◀ in the guide to move to earlier programmes, up to 7 days back where your provider keeps them. Press OK on one to watch it.
  2. Start over. Tuned in late? Start the current programme from the beginning.
  3. Move through time. While watching, ◀ and ▶ jump 10 seconds; hold them to jump minutes. Press BACK in the guide to return to now.
  4. Pause live TV. Pause a channel and carry on later from the same moment, where the channel has replay.
  5. Resume. Left a replay half way? Open it again and choose to resume where you stopped.

Catch-up formats Gridline supports

Providers send replay in different ways. Gridline supports the common ones: Xtream Codes timeshift (in its several URL shapes), Flussonic, and the M3U catch-up types “default”, “append” and “shift”. If one shape fails, it tries the next and remembers what worked.

Questions

Does every IPTV provider have catch-up?

No. Catch-up is kept by the provider, usually for up to 7 days, and not every provider or channel offers it. Without it, live TV, the guide and movies still work.

How many days back can I watch?

As many as your provider keeps, often 7 days. Gridline shows how many days each channel has.

Can an LG TV record IPTV?

Not with a player app on webOS. With catch-up you can watch what aired in the last days without recording.

Why does a replay not play?

The provider may not keep that programme, or uses a replay format the player does not know. Gridline tries the common formats one after another.
