    This must be a bit dumb question, but bare with me..
    This is newbie talking. :)

    I am about to rip/burn a disc, that has 2 movies
    (double feature). The whole disc is 6,3 GB, so it´s
    safe to say, that both movies are under 4,3 GB (so no
    compression needed when burning one movie from
    the disc). There are no extras or subtitles, nor 5.1/
    DTS-tracks.

    I used MTR to rip the disc, and then went to the
    DVD2oneX.

    This "Compression Ratio" got me confused. It says
    (from the "help"):
    ____

    "The Ratio popup-button allows you to select
    between 'Variable', 'Constant' and 'Selective'.

    **Variable Ratio:
    When selecting 'Variable'  the 'old' engine is used for
    processing the movie. This will result in a movie
    quality know from recent versions of DVD2oneX
    v1.2.0.

    **Constant Ratio:
    Selecting 'Constant' will enable the 'new' engine for
    processing the movie. This will result in a much better
    movie quality than known from recent versions of
    DVD2oneX v1.2.0. This mode is especially for
    processing long movies.

    **Selective Ratio:
    Selecting 'Selective' will enable the 'new' selective
    ratio for processing the movie and will enable the
    level popup button at the right side.
    This new engine is a different way of approaching the
    video data! Selectable in three pre-defined levels,
    this new engine determines the balance in distincting
    the important screen parts from the less important
    ones.
    Things that are not in focus in the current frame, like
    backgrounds, are low in detail or as we define it, of
    low importance to the screen and can be approached
    differently than the important ones.
    With this new compression method, setting the popup
    button to low will lead into a scheme where the
    important parts of the screen are a bit more
    compressed than the less important ones.
    Compressing of low important parts can result into
    macroblock because the original encoder in a good
    encoder setup already achieved the best possible
    compression without loss of detail.
    In medium the important parts are even more
    compressed than the non important parts, and in high
    the compression is almost done only on the important
    parts."
    _______

    So what shall I do, since I don´t want compression AT
    ALL?

    Am I using wrong software for this (when I don´t want
    any compression, but I still have to rip the disc, to get
    rid of the other movie).

    Thanks to you all.

    edit: Ok. I guess I have to use "Title Only Extraction"
    from MTR, since I can quite clearly see from the
    timecode which film is which..

    Well, a little "trial and error" and finally it went fine.

    I first used "Title Only Extraction" and then "Title Set
    Extraction" (in MacTheRipper), but they made only
    one ".VOB"-file (title). I burned the other one of those,
    and my DVD-player didn´t recognise it.

    Then I used "Main Feature Extraction", and the film I
    was after (from the 2 in the disc) was marked as "MF".
    Then it worked fine, and it plays on my DVD-player.
    Menu was also there.

    Not sure how will I get the other film if I want (not
    marked as "MF")?

    So "DVD2oneX" doesn´t have "no compression"
    option?

    I try one more time. ;)

    So "DVD2oneX" doesn´t do compression, if it isn´t necessary? Even if I would choose e.g. "constant" or "variable" (and the project is 4.3GB or under)?

    Thanks.
