All media in Public shared even with Media serving disabled

All of the media I have stored in “shared” is showing up over my network via DLNA and Twonky is indexing and serving everything there, even though I have the media sharing option disabled for public.  I just purchased the drive Monday and updated the firmware to the latest release.  Is this just how it works for public?  I would really like to set up a dedicated share for media so I can only share the things I want to stream and not have everything show up - there are so many files it’s pretty much unmanagable.

How are you accessing the files? As a network location or a media share? - If the latter, than you need to configure everything from the Twonky menu’s.
