Where it is
Press Watch now, open the service you chose, and its player carries a download control on phones and tablets. Films, whole seasons, kept for weeks, in HD, with the tracks you chose. That is the 578Movie download people search for, and it works offline.
Space
An HD film is one to three gigabytes; a season of a procedural is ten to twenty. Download over Wi-Fi the night before; set the service's app to standard quality if space is short, because a phone screen cannot show the difference.
Tracks offline
Choose the audio and subtitle language before downloading where the service asks; the offline copy plays with them.
Downloaders
A program or extension calling itself a 578Movie downloader is somebody else's software and is not needed. Nothing on this site downloads a file to your device.
The list offline
My List and the episode marks live in the browser and work without a connection once the page has loaded. Export before a trip if you will switch devices; the file is a few kilobytes.
