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.
