What does EPG channel mapping mean?
EPG channel mapping is the association between a playable channel entry and the corresponding channel in a programme-guide source. It allows schedule records to appear beside the correct media entry in the player.

Mapping can rely on identifiers, names or a manual assignment, depending on the application. Similar broadcaster names may represent different regions or delayed editions, so a close text match is not always correct. If one row is wrong while the rest are accurate, investigate its mapping before changing a global time offset or resetting the entire account.
