I’m having a problem with certain mp4 files where I am only able to watch from the beginning and can’t seek through the file. There are no thumbnails when I drag the position of the playhead and no matter where I drag to, the video just pops straight back to the beginning. Bizarrely, when resuming the video it plays from the last position as expected though.
The files were all ripped from BluRay at 1080p. Other files ripped using the same software/settings work just as expected.
