HELP! DVD Studio pro shows a 3GB movie as 88GB!

Question

I am realy in deep troubles!
Doing a (volentary) documentation about my city, the final doc movie will be shown at 7.januar 2006.
Since 1 1/2 year i am working on DVD projekt and nearly finished.Suddenly DVD Studio pro goes crazy.
I have a lot experiances with iMovie and iDVD but not with Production Suite (FCP + DVD Studio pro) .Maybe i have some misstakes done with FCP or DVD studio pro. But i can't see what and why because during this periode i have burened and check it on TV couple of times bevor.I could cry.
Just have upgraded to the newest Production Studio pro Version and same result.
Ok, one thing i have changed, and later the Problems stared!
In DVD Studio pro you can say how much motion you have.
small, meduim,often i guess (have it in german)
This setting worked and i could one time burn a DVD.
I can say the quality was better, better color and less noise or moire.
I changed it back, but no success.
I have seen in the forum discussion about audio which might
doe troubles and some advises using a.peak tool.
I have checked the aiff files and there are terrible big!
350 MB the biggest. I am totaly confiused because it worked bevor. Have checked the sequenzes from FCP which still works.
What would you suggest first befor i jump out of the window.
Many thanks for any helping hand

Answer 1

Finaly i have solved my problem!
The forum and the helpers did guide me in the right direction.It was not logicaly to me why it work again.
With FCP i could view the sequenz correct.
Then i used compressor-2 with DVD Best Quality, 90min 2 Pass 90min. Best motion. GOP closed.
The output i imported into DVDStudio pro.The import was about 4 minute while bevor it was a few seconds!
I did "clean up" DVDStudio Pro removoed the dvdstudio....plist file -> same result
I did start a new FCP projekt with a new Sequenz, imported all the work i have done befor (lot of work)
and used compressor again.
Then i imported with DVD Studio Pro the compressor files
(this time dolby ac3 audio file) and the import was done very quick.
I could burn the dvd (2.3gb instead of 88GB) and a first quick look this (very early) morning was good!
I chosed this way because i am not sure does working with multiple projekts (not sequenzes) can disturbes the other projekts if they use the same movie. So i will continue with a Projekt, finish them, and start the next from scratch. Hope have no problems like this again ...
