Separate the received channel from its programme listing
If the actual broadcast is one station while the guide describes another, note both identities. A channel can tune correctly while its electronic programme-guide mapping is wrong. Repeatedly rescanning without reviewing that correspondence can leave the important mismatch unexplained.
Use the setup’s mapping stage
Plex’s DVR setup scans the tuner and attempts to match it with a guide lineup using signal type, country and postal code. It then presents received channels alongside their guide channels, with options to select another available lineup, adjust mappings or exclude channels. Plex also documents adding a nearby lineup where a household can legitimately receive stations from another area, and notes that guide data may be absent for some low-power local channels.
Check one identifiable broadcast
For example, compare a station’s visible identity with the channel assigned in the guide during a recognisable bulletin. Review the exact mapping with the administrator before changing a whole lineup or scheduling several recordings from uncertain listings. After an intentional correction, inspect both the live station and the current programme information. Keep the received signal and schedule metadata as separate observations. A corrected label does not create reception of a distant station or guarantee guide data for an unsupported local outlet. For support, provide the received station, chosen lineup and mismatched entry rather than an unrelated playlist or account credential.
Questions, answered
Can the picture be correct while the guide is wrong?
Yes. Plex’s setup treats received channels and their mapped guide entries as separate items to review.
