This is the only way I know,
Windows Features - Turn On or Off
Basically you are just turning it off then turning it back on.
It's under media features.
You might consider disabling WMC then after rebooting your PC, re enable it. See here:
Uninstall, Disable, or Remove Windows 7 Media Center
Might be worth a try!
We have a winner! I finally heard from SiliconDust and, after fooling around with diagnostics, the problem was narrowed down to packet loss due to throttling. Mitchell's link above touched on the solution but didn't give me enough info to work with. SiliconDust provided me a link that went into more detail and, after a lot of head scratching (which left a new hole in my head) trying to figure out to do it, I made the recommended registry change (after first making an image) and the problem appears to have gone away.
It appears I may have created the problem when I made the switch from a Wi-Fi connection to an Eternet connection since the problem started around the same time I made the switch although I didn't make the connection (pardon the pun) until today.
Thanks to everyone for helping out!
