I stream movies and music on my Directv system all the time. I recently got a new PC running windows 8. Everything seems to be set up properly but the mediashare icon constantly disappears. One day it is there and working and when I turn off the system the next time I turn it on the icon is gone. I have to reset the system 5 -6 times to get it back and it doesn't always work. I also run the PlayOn server to stream movies from Netflix. When the icon is present these systems all work fine but I just can't seem to figure out why the icon keeps disappearing. All Directv tech support can tell me is to reset the system. I have called them at least 30 times about this and that is all they ever say. Does anyone else have this issue and have any idea how I can fix it?
