If this has already been mentioned, I apologize. I tried out the new release and while it seems to have some improvements, it has a big drawback, at least on the one machine I "upgraded" on. I have been running WMC v.11 on this machine and it performs beautifully. So I let the Insider Fast Ring load the latest unpolished build as above. All went well, things look good but for WMC. I reloaded HDHomerun Prime, scanned the 364 channels (lots of music channels) and did the proper installation of WMC v.11. All looked good until setup barely started. The dreaded "No Tuners Found" came up everytime I uninstalled, booted and tried re-install. After checking firewall permissions (good), adding NETWORK SERVICE and a few other things with repeated uninstall, install, try, fail and two hours passed I rolled back to build 10586.63 and after installation all is good. I'm unable to figure what happened to block the tuners from WMC when they will play in the HDHomeRun View application. Just information for thought.
