A check for ESPN
Identify the event and exact network label shown in ESPN's listing. If the guide points to ESPN but the event page lists another service or ESPN network, use the event page to identify the authorized route for your market.
Check the station edition
Record one programme and its scheduled local time on the broadcaster page. Compare it with the channel label and time displayed in your player.
Check the guide if the live feed works
If the programme matches the live edition but the guide is wrong, confirm the channel mapping before changing the device clock.
