2 pass VBR get better result, but difficult in captured leng

[SingSing]

I encoded "lord of the ring" DVD rip in 2 pass vbr for svcd flim.
The bit rate are 2520-max, 2000-average, 1600-min.

The results are better with less pixelation.

But compare to CBR the movie at 2200 that convertered
to four 700MB CDs, the amount
of movie per CD is difficult to predit. Some of the four
disc is more than 700 MB, some of them are the same,
some of them are less.

It really did not help me to squeeze them in 3 CDs.

Did I did some thing wrong ?

Also, what template script lines do I did to change to
go beyond 2520 bit rate ? Does higher bit rate make the
disc a XSVCD, and less universal ?

What did you use to split them? You would typically split them after the entire project was encoded, to maximize the space used to 800MB per CD.
You should also use a lower MINIMUM setting (300 or even 0 is preferable). For the average try 2200, for the Max setting try 2500.

If you increase the bitrate beyond the SVCD maximum, then yes, you are making an xSVCD, which won't play on all standalones. You will also increase the size of your movie, and increase the amount of space (CD's) needed to store it.
