Saving the name is not downloading the film
The heart on a title card adds that production to My List. It is a reminder you can return to, not a video file. The backup controls copy those saved choices and episode checkpoints as text.
For a journey without a connection
Some viewing services offer offline downloads inside their own applications. Check the particular title, supported device, account requirements and any expiry shown by that service before leaving. A film available to stream is not automatically available to download.
Open the downloaded item in the intended app before the journey to confirm it is ready. Storage space, language selection and playback permissions can affect the result. Keep those checks with the service supplying the download.
VidSrc2 does not supply movie-file or APK downloads. Find the production, then compare the options attached to its Watch now link.
