EPG (Electronic Program Guide) is what displays what is currently playing on each channel, what is coming next, and program details. How XMLTV Syncs Obsidian IPTV generates EPG files in XMLTV format. Every hour, our server crawls television networks globally and compiles program logs into a compressed XML file. Your player app downloads this file once a day, updating the program guide on your screen. Troubleshooting Empty Guides If your EPG is displaying blank rows, try the following: 1. Clear the EPG cache inside your player settings. 2. Verify that the EPG URL is exactly correct (ensure no trailing spaces or typos). 3. Force a manual update in settings. Syncing EPG on low-memory devices can sometimes take up to 2-3 minutes, so keep your player open while the download completes.
