Shotaway:
After you have ripped the VOB files then use DVD2AVI, Select ADD and then select your first VOB file normally 1...  It should select all the  related VOB files with the first........
After that click Save project,  This takes about 30mins 
After this, then use the Vfapi converter and open your DVD2AVI project ie:  Matrixd2v.prj   or something similiar
After this is done then use VDUB and select the dummy avi created by Vfapi, you must have the Vfapi codec installed..
Also make sure that you select .Wav audio and then browse for the Wav for the film you just ripped..  The Wav is made from DVD2AVI
