Check coverage before editing
A readable XMLTV file can contain channels with no upcoming programme entries. Look for a current start date and a programme linked to one known channel. Keep the device time accurate so an expired batch cannot look current. If your player supports multiple guide sources, isolate one source during the test.
Test three outcomes
- Every channel missing. Confirm the guide URL is valid and authorized, then check the last retrieval and whether the file can be opened.
- One channel missing. Compare the playlist key, XMLTV channel ID and the feed region.
- Current day appears, future days are blank. Ask the guide source what dates it publishes and check the latest batch before clearing a working setup.
Keep the working pieces
Keep the playlist and password as they are while investigating the guide. Document the last successful refresh and the first blank day. That gives the supplier something more specific to investigate than “EPG not working.”
