Name the movement you want to change
Notice whether the unwanted motion is an expanding poster, scrolling background, automatically playing trailer or movement inside the actual programme. Different controls apply to different layers. A preference that quiets a menu is not a general filter for all movement in a film.
Apple TV documents Reduce Motion and an option to disable autoplay video previews in supported apps. These controls have defined scope. A third-party player with its own animation system may provide a separate preference or may need an app update to respond.
Make browsing the test
Use a short repeatable route: enter the home screen, highlight several top-row items, open a details page and return. Change one motion or preview preference and run that route again. Check both the movement and the clarity of the focus indicator. Reducing animation is useful only if you can still tell where you are.
Then enter the particular player. Identify which changes carry across and which do not. Recording a specific remaining preview is more helpful than reporting that accessibility settings do nothing. The operating system cannot guarantee that every app draws its own interface in the same way.
Keep programme controls separate
If the difficulty occurs during the programme itself, use the appropriate documented accessibility features or content information. Do not assume a menu-motion preference changes camera movement, flashes or programme editing. A title may also carry an advisory, but catalogue wording varies.
For shared televisions, discuss whether autoplay previews should stay off as a household default. A reversible system preference can be easier to maintain than repeatedly avoiding a particular tile. Recheck after major app or system changes if the behaviour returns.
A precise support request
Describe the screen, the animation and the setting that was enabled. Include whether the same behaviour occurs in Apple's own menus. A short factual report such as a trailer still starts on the details screen is easier to investigate than a general claim that motion reduction failed.
Apple's support material establishes the system options and their supported-app qualification. This site has not run a motion-sensitivity assessment of an IPTV app, and the article does not promise that every programme will be suitable for every viewer.
