i tried to convert one movie to cvcd with quantization 5 and the resulting file was 13 mb bigger than 1 cd so it was split into two parts. then i tried quantization of 6 and then the file was about 40 mb smaller than 1 cd. so is it really supposed to create file fitting on 1 cd? to me it seemed as if i go for higher quality (smaller quantization value) i get bigger files. if it really is attempting to create file fitting on one cd then do i need to change the calculation of bitrate somehow to get something less for q=5 or more for q=6?

The truth is it's quite hard to guess the future size using one pass variable bitrate. The calculations are based on trial & error, but some times they can fail.

You can't set an "average bitrate" with one pass, you can only set "max bitrate", and quantization, so my method was to use as "max bitrate" the ideal "average birate" + 5%. But if you have a file with lots of action, maybe it will use "max bitrate" all the time, so it will oversize. So you can remove the line under # +5% in the script, or change the quantum value as you did.

If you do more trial & error, may be you could recommend me the best values which worked for you

Yes, look at the date of the message! . One year ago, there were only scripts for VCD, SVCD and CVCD, so CVCD was the best of them.

Of course now the best (for me) is KVCD.
