When I use the AC3 encoding option, then audio and video is out of sync.

When I press "A" and set the sync to -50ms then everything is fine. However I need to do that every time I start the playback of a movie.

Is there a way to set -50ms globally so that I don't have to do this all the time?

I can't do this on my Onkyo because that then puts the audio out of sync on my Playstation 4 and the dvb-s receiver.

You can set defaults via the OSD menus during a video.
Either for audio offset or for subtitle offset.

Then select "Save as default for all video files" (or something similar).

You can also adjust settings via the advancedsettings.xml (wiki) file. Look in the wiki page for more details at #2.2.2
Example:

PHP Code:

<refresh>
  <min>23</min>
  <max>24</max>
  <delay>125</delay>
</refresh>
