Good morning, I searched for this topic but had no luck. I have been using Plex for over 7 months with no issues, it recognizes my DVD and BD rips and works perfectly. About two weeks ago, however, the new BD rips stopped being recognized. I am using BD Ripper 10.0.4.3, and when I rip a movie I receive no errors from DVDFab, but the movie will not be seen by Plex. I have worked with Plex support and according to their tools the issue is the file isn't valid. The tool indicates that it "could not find tag for codec hdmv_pgs_subtitle in stream #2, codec not currently supported in container". I can play the rip using Windows Media Player, however. I have tried different formats (MP4, MPEG, MKV) with the same results. When I used MakeMKV I had no issue with Plex, it recognized the movie right away. Luckily my old rips are fine, this issue is just with movies I am trying to rip now. Did DVDFab change something a few weeks ago? What could cause this?
