CCE SP 2.5 check sum error

[SHARKO]

I'm using doom9 dvd9 to dvd5 guide, also "getting the best out of CCE"
1st pass goes well, But if I try VBR multipass set to 2, or like "getting best..." informs you to edit 1st pass and set the 2nd pass VBR multipass to 1. When 2nd pass finishs it pops up a error about the CHECK SUMS between passes do not match.
I'm using:
smartripper 2.41
dvd2avi 1.76
avisynth
CCE SP 2.5
chapterXtractor
bitrateviewer
maestro 2.9
Any help?? I'm follwing guides "exactly", all works well except CCE on mutipass-THANKS-

Go to the CCE forum on doom9. You'll find the CCE FAQ which covers this. You need to install a patch which disables the checksum checks.
