    I selected the AVI file, then under advanced:

    Constant Output Quality
    Highest Quality
    Split Setting / DVD Capacity: 8500MB
    Enable DVD Chapter (150)

    And yet when it outputs the total file size is only about 4.5GB. Why is it not the size of a DL dvd?

    With CQ, the true bit-rate is not known before the encoding is done,
    (it depends on the complexity/quality of the input file),
    and secondly, the length (in hours/minutes) of the source is a factor.
