I've been using WMC on WIn7 64bit for about 2 years now. I have two HD homerum Primes and generally have been pretty happy. But for the last month or two I get popups on the tv with the XB360 extender saying no tuners available for recording. I check the tv signal setup and it only shows 2 tuners, the 2 different HDHRP. I rerun Tunersalad and it shows 6 tuners again. And it will work fine for a few weeks, or a month, or one day, and then resets to 2 tuners.
Any idea why the number of tuners can reset?
