@babgvant I have found an issue in the v2.0 emby theater where Anamorphic DVDs converted to mkv format are not displayed properly.
Emby seems to follow the video pixel width parameter (720) in the mkv header, but not the display width parameter (853).
This results in the video being player back in 4:3 (720x480) instead of 1.78 ratio (853x480).
All other players seem to follow the display width including Emby server.
Has anyone else had this issue?
