Emby is the alternative to Plex, with Emby Premiere being the alternative to Plexpass.
It only ever goes on sale once a year at Black Friday. US $20 off isn't much, but better than nothing.
Emby Premiere gives you:
* Offline Media (download to smartphone)
* DVR
* Free mobile apps
* Styled Cover Art
* Cinema Mode
* Cloud Sync
* Emby Theatre
* Automatic file conversion
* Folder sync
* Backup & Restore
* Podcasts
* Smarthome integration
I've been using Emby over Plex as it lets me blacklist content for specific users in the house (something Plex ridiculously cannot do), and I was getting a little bit tired of the attitude of the Plex devs towards their users. Not to mention the whole Plex Privacy Policy/Telemetry data controversy a while back.
