Change one channel at a time and allow the player to show a clear result before switching again. Rapid input can queue interface actions or repeatedly open and close media requests. A deliberate short comparison produces more useful evidence than racing through dozens of entries.
Choose a small relevant sample
Use a few familiar entries from the categories you actually watch. Note whether each starts, fails or remains loading. A catalogue-wide claim based on a fast sequence of button presses can overlook the app’s normal transition behaviour.
Watch for delayed input
A slow interface can process several queued remote presses after you stop pressing. The selected channel may then differ from the one you intended to test. Wait for the focus and label to settle before interpreting the playback result.
Report the transition precisely
If switching consistently fails after a particular action, describe the starting item, target item and visible message. Keep the device and player unchanged during the test. This can distinguish a navigation sequence problem from an isolated source that does not respond.
