Seconding Stremio! Just had to install the Torrentio add-on and even my tech-challenged mom can use it on her Android TV with no problems. I also got her a RealDebrid account (9 EUR/6 months iirc, completely optional) so she doesn’t have to deal with torrent seeds etc.

Indonesian does; kiri (left) and kanan (right). “Ki” and “Ka” are usually used in texts (e.g., for captions in newspaper/magazine articles), but for headphones, contact lenses, etc it’s normally just L/R.
