Blue Ray to DVD only does the main movie at this time.  That's what Vivian from tech support told me recently.
I hope that this will be worked on sometime soon.  I'm reading posts from 3 years ago and back then it was said, "coming soon".  
I recently started trying the Blu-ray recording again.  Last time I took a look at this it was too expensive so I went back to DVD to DVD recording.  I do enjoy the extra content, menus, commentary, etc that is provided on "some" disks.  But it appears some of the studios are now only putting the "extra" content onto the Blu-ray versions of the disks.  So I have a motivation to get back into Blu-ray recording.  It's still too expensive in my opinion, but Blu-ray to DVD?  Hmm, that's affordable.  But unfortunately DVDFab doesn't do the extras yet.
Any ideas on when this might be scheduled?  I buy a lifetime in a heartbeat if it was working.
