Confirm that the feature applies
The publisher’s guide limits the feature to movies in desktop Xtream sources at the check date. Series, M3U lists, Stalker portals and browser use should not be assumed to expose the same source chip. Check the installed release and source type before troubleshooting an absent control.
A source must already be part of your authorised library. Two copies with a similar title can still be different films or editions. Confirm the year and other identifying details before comparing them, especially for remakes.
Inspect the copies before choosing
Open the supported Sources control and review the available copies. The publisher distinguishes API-reported properties from guesses inferred from names; an advertised resolution in a title should not be treated as measured output. A copy not yet checked is also different from one reported unavailable.
Choose a short practical comparison that matters to you, such as the intended audio language or a stable passage. Use only accounts and media you may access. Do not purchase an additional subscription merely because a feature promises to make switching convenient.
Keep continuity and identity separate
The documented switch can continue at the same time position, but two editions can have different introductions, cuts or audio. Check the scene after switching rather than assuming the same timestamp means exactly the same point in every copy.
Playback progress is associated with each copy. A preferred source can also influence which saved position a later Play or Resume action uses. Keep that behaviour in mind before reporting that a film unexpectedly resumed from another point.
Use automatic recovery with clear limits
The guide describes optional automatic switching for supported built-in paths and an announcement when a switch occurs. An external player’s independent window does not necessarily report errors back in the same way. Check the active engine before relying on automatic recovery.
If a copy repeatedly fails, record the actual source and error instead of allowing automatic changes to conceal every failure. A smooth switch is useful viewing behaviour, but it does not prove that all copies are equivalent, every account is active or the entire catalogue has been tested.
