I am seeing stuttering from time to time with some rips. They should all be done in the same manner, no DTS or Dolby sound in them, no fancy codecs. I think Kodi 18.1 is broken on audio, video is running fine, but audio gets garbled, as if buffering would be empty. I do not want to go back to Kodi 17, it is a royal pain in the behind to redo the setup, with addons, even though I know I have a backup done with the backup plugin.
