A player close to the live edge has less stored media to cover interruptions. A longer buffer adds delay but can absorb a short delivery gap. The useful balance depends on the stream, player and connection.
Recognise where delay appears
Encoding, packaging, transport and player buffering all contribute. Two screens showing the same event can be several moments apart even on the same router. That difference does not automatically mean one connection is faulty.
Change only supported settings
If the player offers a live-delay or buffer option, note its original value and test a modest change. Unsupported tweaks or unrelated developer settings can make results harder to interpret. Leave enough viewing time to judge repeated behaviour.
Keep expectations realistic
Reducing the player buffer does not remove delay already introduced upstream. If the feed is consistently behind another service, the cause may be outside the home. Report the source and comparison without assuming every second can be removed locally.
