Jongens het is allemaal opgelost.
Alles werkt zoals ik schreef lag het hoogstwaarschijnlijk aan Microsoft Office 2016 en / of MplayerX.
Tevens had ik al opgeschreven suggesties al gedaan en telkens bij het installeren van 1 of beide programma's kreeg ik een blanco folder van Vlc.
Nu niet weer alles werkt zoals het hoort en het is genieten.
Desalniettemin bedankt voor de reacties.
