I did a fresh install of win7 on my htpc, all updated drivers, the same problem still occurs. I did the network test and for a little over an hour I got a few "s" but no "n" but I still get a frozen screen every 15-20minutes or so and sometime it will cause WMC to crash and/or I have to restart it. Most of the times it will freeze from 5 seconds - 30 seconds and then come back normal.
I tried to tweak the registry by doing some research and even added another drive to do buffering as was suggested but the problem didn't get better or worst.
I am at a complete loss, is it possible or likely I have a bad hd homerun prime unit?
Is Ceton any better at this? I may try that route but I invested so much time in this, I would hate to abandon it.
