Compare Language Options Across Sources
Keep the title and episode fixed while comparing language options across sources. A server switch changes the player or assets, so inspect each source's actual audio and subtitle menus rather than infer options from its name or the catalogue's country labels.
Record the starting combination
Note the selected server, audio language and caption language where those choices are offered. Confirm Now Playing for a show. This gives the comparison a clear baseline instead of relying on a memory of what another episode previously supplied.
Check each menu again after switching
A source may provide different tracks, controls or defaults. Verify audio and captions independently, then start playback to confirm the selected content. A shared title page does not imply identical files or language coverage across all available servers.
If checking the menus reveals a fault, Work Through Sound and Caption Problems explains the next observations to collect.
Report absence and failure separately
An unlisted language is an availability observation; a listed track that plays incorrectly is a different symptom. Include that distinction in feedback. Neither case establishes that a production-country association is wrong, because metadata and source language are separate attributes.
