TMPG CQ gone crazy

[canoner]

Read the log file below. The sequence of CQ values TMPG used diverger, not converge! And then just settled for a value it knows too high! This is beyond me. I have used TMPG CQ for a while and been pretty happy with it.

Prediction is not an exact science :D

You might try increasing the "Frames pr spread" and "Spread" parameters in the dvd2svcd.ini file to let D2S have a larger and more representative section of the movie.

It will take more on every try, but should converge faster.

The way DVD2SVCD does it's CQ quesstimation does seem a little radical at times but you requested two CD's and ended up with two CD's. So why do you think the value is to high? If you ended up with three CD's I could see your problem.

Copy and Paste from log file:
"- Encoding Test Clip C:\Program Files\DVD2SVCD\Movie\Schmit\AviSynth_Script_file_CQ_TEST.avs
Wanted: 1471899402 (1437402kb) Predicted: 1990959751 (1944297kb) Using CQ Value: 93.68

"

It settled for 93.68 although its prediction is 1990959751 while the wanted is 1471899402. It is not working in order! Besides, the second MPG file is like 1400MB and the CD image couldn't be made.

I am not asking how to make it predict better or faster, but why it is working totally out of order. First, it should try converging sequence of values, not diverging sequence. Second, it can't settle on a CQ value with which TMPG predict a size 500MG more than wanted size.
