BDMV structure DVDFab detection

Hello,

I’m evaluating DVDFab Platinum 4.0.0.5 and would like to create an AVI file from a Blu-ray structure (BDMV directory) stored on the hard disk.
It appears that DVDFab 4.0.0.5 does not detect the blu-ray structure.
Is it normal or is there mean to do that with dvdfab ?
