To get around the problem of out of sync playback, In kodi you can slide the audio to be in sync. while playing an out of sync clip, press the 'ok' button on the remote. Kodi's UI will now be on the screen. Move over to the right to the speaker sound settings icon. In here there is a setting where you can slide the audio to be in sync. For me, I have found that moving the slider to the right, to about .250 or so, will bring the audio back in sync. You may need to set Kodi's main configurations to be an advanced user if you do not see this setting. Kurt
