Open the authorized source privately and note whether it is a channel list or a single stream. Play one item on Windows and the intended television. Record the network, player versions and time window. Choose the same quality where both allow it.

If Windows opens the item while the TV fails, check what codec or variant each selected before changing the TV's decoder. If both devices fail for one item while another works, report the station and error. If neither device plays any item, verify the account and source retrieval separately.
