How do you convert? In Qt GUI (Windows/Linux) you can use Streaming wizard (Media > Stream...) instead of Converting wizard (Media > Convert/Save...) as it contains a checkbox for the option ([ ] Stream all elementary streams) in the last step there or you can manually edit (add) options in the Open Media dialog window ([v] Show more options > Edit Options input field).
