High CPU usage with HDhomerun

I have a windows 10 pc with and amd A10 processor and an nvidia gtx960 video card on Kodi 16.1 and get very high cpu usage when using the HDhomerun addon. Are there any setting that I might need to change from default? You can really hear the CPU fans humming along after just a few minutes of use. Any help is greatly appreciated. This problem has been happening for quite a while now.
