Find where the interruption begins
If search and title pages work, the catalogue is loading. If a viewing offer fails after Watch now, check that destination. If the player opens but buffers, test the connection and the player's supported quality options. Each situation points toward a different remedy.
Streaming servers and source choices
Use only the source controls offered by the actual player. Some services manage delivery automatically; others expose choices. This catalogue does not supply a separate list of active video servers. Repeatedly switching unrelated pages is not the same as changing the video's source.
Audio without sound
Check mute, the player's volume and the device's output destination. A connected headset or receiver may still be selected. If the picture has no sound only after casting, compare the TV input and the output method before changing the browser.
Speed, shortcuts and Picture-in-Picture
These depend on the player and browser. Check the visible controls or that service's help. Keyboard actions can behave differently when focus is outside the video. Use TV and casting help for larger-screen problems and not-working help for a blank catalogue.
