The problem turned out to be that the xml file containing the recording information was corrupt. I finally found a solution to the problem but unfortunately it meant erasing the file and loosing all of your recording info, which you will need to recreate. Follow this and it will work:
1. Right click on “Computer” and select “Manage”.
2. Open up the services and get ready to temporarily shut down the “Windows Media Center Scheduler Service” and “Windows Media Center Receiver Service”.
3. Open up the following directory “C:ProgramDataMicrosofteHomeRecording”.
4. Shut down both of the Media Center services in #2 above and quickly rename (or delete) the “Recording.xml” and “Recording.xml.bak” (the Media Center Services restart for some reason and you can’t properly delete the recording schedule data without having them shut down).
5. Start the service “Windows Media Center Service Launcher” (this will start both of the other services correctly).
After this, Media Center will recreate the Recordings.xml file and you can reprogram your scheduled recordings.
