Need help on DVD Packaging Info
 

I recently seen Wal Mart selling the repackaged DVD's for Buffy the Vampire Slayer and Angel. This is the third time the series have been repackaged, first the big sets, then the slim sets with the individual cases inside, and now they are published in a DVD case which is the same size as a regular DVD movie you would buy. Season Five of Buffy and a few Angel's are not available at all the Wal Marts I went to. Does anyone know the "official term" for the DVD packaging I am looking for. It is the same as a normal movie you would buy as in width and all, but when you open the case it flips the disc. I hope I described that enough. I want to know so that I can narrow my search down to find this specific packaging online. Thanks!
