I have a few mkv files where the audio will just not sync up. When I was running mediatomb there was a way in my transcoding script i could add options for ffmpeg (one being -async) which fixed the problem before. Is there a way to add an option like this to advanced options or something? basically it just did an audio sync for so many samples per second so I typically set it to 2 and on these mkv's they would sound normal. Just not sure how to do it with PSM
