I was having a very similar issue after the recent upgrade to the latest version, my steps to resolve include. 1 - Downloading the channel fixer,Channel Fixer , and pointing it to the location of the db it populates 2 -Then using the button at the bottom I was able to remove all Tuner dvr data. 3 - Closing PMS from the task bar, i relaunched PMS and was greeted to a popup stating it has found an HDhomerun device and, would i like to setup DVR?
