Re: using "hdiutil create" to make DVD image

I found an open-source program called Burn that I've been impressed with.   I believe it uses Apple's DiscRecording framework to accomplish its features.

The linked technique uses the makehybrid verb for hdiutil.  I am wondering if the same can be accomplished by using the create verb.  So, I created a home movie using iDVD, and copied the VIDEO_TS and AUDIO_TS folders to a new folder on my hard drive (TEST).

$ hdiutil create -fs UDF -srcfolder TEST DVDminimal
mount_udf: mount_udf: open /dev/disk3 failed, Resource busy: Resource busy
/sbin/mount failed with error 256

I can open the image and see all the files fine, despite the mount error when creating the image.  I burned this to a DVD-R using DiskUtility.  But when I insert it into my Mac's drive, I get a "You inserted a blank disk" dialog.

So, either the creation did not produce a proper disk image, or the burning produced an improper DVD.  Anyone have an idea about this?
