    Hi,I'm quite new to all this and I need some
    answers.They mostly have to do with the
    divx's parameters.First of all,I have read
    many guides,and sometimes they say exactly
    the opposite!Well,here are my questions....

    1)Is it good to check the "MAX CPU Usage"?
    If yes,what do I "gain" from that?

    2)[The most important one] What does this
    "Default postprocessing level" do? In one
    guide I read that this is good,and I should
    move the slider to the 2nd or the 3rd
    "place".In one other guide,I read that I
    SHOULDN'T touch this slider...What should I
    do?

    3)Which is the best max-min quantizer combo
    for great quality at a reasonable size?
    (I usually want to fit a movie to 2 700MB
    CD's)

    4)And now a Graphedit question.I use these
    filters: I-Media multiple MPEG2 source ->
    Ligos MPEG2 splitter-> Intervideo Audio
    decoder ->WAV dest ->File writer
    Well,in some movies the sound "jumps" every
    half an hour! It's annoying! Should I use
    another filter combination?

    5)And lastly a "Lame" question.In
    "Operational options" ,should I use Mode:
    "Stereo" or "Joint Stereo"? What's the
    difference?

    Thanks for your time.Any answer(or comment)
    should be deeply appreciated.
    Thank you.

    I can't answer all the questions without little investigating, my memory is not the same as it used to be ;-) But here goes:

    1) MAX CPU Usage means just how much CPU time you wish your encoder to take from you -- if you encode during night while you're sleeping, select it. If you prefer doing something else while it's encoding (like browse the Web), don't select it

    2) If you play your DivX4 encoded videos with, let's say, Windows Media Player and go to codec options (Properties, etc..) you see various values that you can change for the DivX playback. One of those is "postprocessing level". Higher it is, more your computer tries to "make the video look better" while playing it. Setting it to highest kills easily P4/1GHz machine, as postprocessing takes helluva lot of CPU power. "Default postprocessing level" basically means that your video is set to use, let's say zero, as a default. User can change this whenever he wants, so it's not a _real_ problem, but 99% of the people don't even know that they can change DivX's playback settings, so it's good to keep it as zero, so videos play smoothly even with slower computers without going through the hassle of changing it manually.

    3) This only applies to 1-pass encoding and 1-pass is not recommended.

    4) dunnoshitaboutthisone :)

    5) Stereo is the choice you should always use for MP3 bitrates higher than 128kbps. Joint stereo encodes both audio channels together creating "fake" stereo (not mono, but fake stereo) and saves a little bit of bitrate, but when you're using 160kbps or higher, it's always wiser to use Stereo as it sounds better.
