I can set up Live TV in Windows Media Center (I am using a set-top box) and everything works properly. However, eventually I lose the ability to change channels in Live TV. They will not chage via the keyboard, Windows Remote, or using the mouse in the WMC window. The channel number will display in the WMC window but it seems communication is lost with set-top box and the channel will not change. They will change with the set-top box remote. If I go through the set up process again, the channel change function will work for a while and then stop.



Any ideas?
