When you replace the hard disk drive, you can no longer play any previously recorded TV programs.
Important information about recorded TV programs
When you replace the hard disk drive, you lose any files or software that you created, saved, or installed on the PC. Because of this, you also lose a special code that Microsoft includes in the files of recorded TV programs. Without the code, Media Center will not play TV programs previously recorded to disk, or copied to DVD or to other media.
