When playing some video's, MP could crash randomly.

Something with AccessViolationException error

Nothing wrong on my own system (see system specs)..

Somebody? I don't have an idea.. Disabled all plugins.. still the same error:
System.AccessViolationException: Poging tot het lezen of schrijven van beveiligd geheugen. Dit duidt er vaak op dat ander geheugen is beschadigd.

And after this, many more error's to come, like this one:
Fout in de toepassing.
