Mezzmo server advertises itself across all your network adaptors on your computer in order to communicate with your DLNA devices, so if you have multiple networks cards (and/or virtual adaptors), then this would explain why you are seeing multiple Mezzmo servers listed on your devices. If you don't have multiple network adaptors, then we'd like to see your "MezzmoMediaServer.ini" configuration file (email it to us at support [at] conceiva [dot] com). You can find this file in the following folder:
C:\Users\<username>\AppData\Local\Conceiva\Mezzmo (for Win8/Win7/Vista)
C:\Documents and Settings\<username>\Local Settings\Application Data\Conceiva\Mezzmo (for Win XP)
