I recently got a new computer running Vista. I decided it was time to network to my HR-20. I got a WGA and after some fumbling around I managed to get the HR-20 connected to my wireless network and to the internet. When I went into Windows Media Center 11 on my computer and the tools, options, configure sharing procedure I did not find the HR-20 (unknown device) listed. The only thing listed was a single item--Other Users of This PC. Any ideas on what to do next?
