I currently use Netflix, Amazon Prime and Plex.
Next week we are off on holiday and therefore I bought a 500GB hard disk expecting to be able to offline content and watch it back when away - more than likely to have poor internet.
The AndroidTV apps seem to be built not to have offline capability
Is there anything I should look at other than VLC / Kodi?
MX Player has been a reliable client for local video playback.
