If you follow my directions you should be able to make a 25 gig full disk or main movie the 3d files are their even though you can't see them just burn the disk with fab burning engine checked in soft wear its the default anyway.If you made a 25 gig iso then you can burn with img burn so the rule is if you have a 25 gig 3d movie as a folder to burn it must be burned with fabs burning engine if you made a 25 gig iso then img burn or fab burner can be used for the burn this keeps the 3d files in 3d.
Open fab,select main movie, in the pull down box select 25 gigs,hit next page their you will see make 3d movie already checked for you then hit start,fab will compress the 3d movie to whatever you selected in the pull down box and then it will burn the disk for you in 3d so make sure there's a blank disk in the drive.
The disk should come out about 22.5 gigs or so in full 3d.
