Plex convert. Not the first I’m sure.

Awesome app. Well worth the very cheap price. Ripped all my Blu-rays too an external hdd plugged into an Apple AirPort Extreme. Put the on everyone’s Apple TV and bam. Blu-ray quality everywhere faultlessly apart from odd drop. My only criticism is the organisation of films. Harry Potters all in different order, Ironman 1-3 too. Need an alphabetical and date option. And possibly lock capability for older films.
Overall awesome. Drop plex or whatever your using and get this.
