Hi all, Hoping this question is an easy one. I recently purchased an Apple Mac Mini to use as an HTPC and running Plex (all movies are ripped via MakeMKV and stored on a 1.5 TB external HD connected via FW800). In searching though my Mini's internal HD, I noticed there were several pre-loaded movies in the iTunes Movies folder (40 Yr Old Virgin, Fantastic Four, etc.). I copied the folders to my external HD and added the files to my Plex library. When I playback the movies (MP4) via Plex, the picture quality is terrible (like when you expand a YouTube window and the resolution is awful). Make MKV won't recognize the MP4 file to convert to mkv (the file is grayed out). Here's my question: How do I get the MP4 to play in Plex with good video quality and/or how do I convert these MP4 files to mkv? Thanks!
