CCleaner and Windows Media Center

Last Saturday night, I installed CCleaner on two Media Center boxes. One is in use as my PVR, the other is a friend's desktop (no PVR installed).

Both machines are now exhibiting some pretty weird errors.

First, my PVR now boots to a "Failed to initialize Infrared Remote Hardware" error, and it won't record TV now. I am...less than pleased.

My friend's machine can't play dvr-ms files (the default MC file type) in either MC, or in Windows Media Player, despite having proper codecs.

CCleaner was run with all options on, save for "Cookies" and "Autocomplete form history"

If you're on Windows Me or XP use a System Restore point to restore your system(s) to an earily date.

Edit:

If System Restore doesn't help reinstall Windows Media Player.
