• When the scan completes, the SFC utility will indicate whether or not it has found any problems and whether or not it was able to fix them.
• If any errors are reported that SFC was unable to fix, please refer to the following Microsoft support article:

In case you can't fix the problems with Windows Media Center with the above mentioned instructions, this can be caused by a corrupted recording schedule recording shedule data (Recordings.xml).

You may try to delete the following file

Users\All Users\Microsoft\eHome\Recording\Recordings.xml

Please note that it will clear all your scheduled recordings.

You can try to rename a backup of Recording.xml to Recording.xml after deleting the corrupted file.

If all the above mentioned doesn't help you can try to use System Restore to restore to a point prior to a date/time that the problem started. If you don't have a restore point that can fix that, you may need to try to repair/re-install your Windows Vista.
