I have HDHR V2 (http://hdhrviewer.zynine.net/) working with no issue on a Windows 10 installation of Plex Server but I am getting this "Streaming this media is unsupported" error on a new Plex Server installation on a Windows 7 PC. Both computers have older Core I7 processors (M620 @2.67Ghz vs Q840 @ 1.87GHz, respectively). Homerun Viewer and VLC play without issue. I have installed CCCP Combined Community Codec Pack for the heck of it anyway. Also have older pre-beta versions of HDHR plugin, no difference.
Any ideas would be appreciated. Thank you,
J
