Pretty sure that unless the contents change, meaning different specials on a disc together, that all the rereleases are the same transfers, just repackaged.
I know this is the case for Snoopy and Friends and Charlie Brown and Friends, which are just repackaged versions of Snoopy’s Reunion and disc 2 from 70s Vol. 2. 99% sure all different releases of the Christmas, Halloween and Thanksgiving DVDS are the same discs from the first WB releases.
