Compare identity before time
Note the channel label in the player and the programme shown in the guide. If possible, compare several consecutive listings rather than only the current programme. A schedule that belongs to another feed may remain wrong throughout the day.
Similar names, HD labels or shared logos do not establish identical schedules. Regional and time-shifted feeds can differ, and an old saved favourite may point to a different entry from the one now shown in the main list.
Understand mapping identifiers
XMLTV programme records reference channel identifiers. A player or service needs a suitable relationship between those identifiers and the channel entries it presents. Display names alone do not necessarily provide a reliable match.
If your player exposes a supported mapping tool, read its documentation before editing. Save the existing relationship so it can be restored. Do not paste private playlist or guide data into an unknown online matching service.
Use a small verification set
Choose the affected channel and another channel whose schedule is known. Compare the current and next programme, the local time and the feed label. If a mapping correction fixes one entry, check the following listings as well.
A time offset moves the schedule but cannot turn another channel’s programmes into the correct ones. If the titles are fundamentally unrelated, investigate identity and mapping before clock conversion.
Report the mapping evidence
Give support the displayed channel name, the programme it actually shows, the programme the guide claims and the relevant date/time. Include a feed or regional label when visible.
Do not publish account identifiers, full guide URLs or customer records to demonstrate the mismatch. A redacted pair of labels and a written example is usually enough to explain the problem. Keep any manual mapping change documented for the next guide update.
Questions about this guide
Can a one-hour offset fix another channel’s schedule?
No. It changes timing, not channel identity. Check mapping when the programme titles do not match the feed.
Are two channels with the same logo necessarily identical?
No. Artwork can be shared across regional or other feed variants. Use the actual feed identity and schedule.
