After enabling media sharing, the PowerDVD server appeared on my home network. I then disabled it with the setting "Do no share media with any home media (DLNA) clients." Despite this change, the PowerDVD still broadcase on my home network. This persisted through reboots. Only uninstalling PowerDVD removed it.
System: Microsoft Windows 8 Enterprise x64, CyberLink PowerDVD Ultra Version 12.0.2118a.57.
