    The quality is exactly the same between the two settings. Which you choose depends on your goal.

    System muxes the video and audio together to create a single .mpg file.
    Elementary does not mux. The output is a video .mpv file and the audio is a .mpa/.ac3 file.

    Some DVD authoring programs require elementary streams and do not accept system streams.

    Elementary streams can be muxed after encode to create a .mpg, and a .mpg can be demuxed to get the elementary streams.
