My DVD
won’t play.
You can put data files on a DVD to store them or transfer them to another 
PC. However, data files on a DVD do not play in a DVD player. Rerecord 
your files to a file format that can be read by some DVD players.
Codec errors are 
occurring when I 
play certain files.
Codec is an abbreviation for compressor-decompressor. A codec is 
software or hardware used to compress and decompress digital media.
If you get a codec error when playing an audio file, open the file in 
Windows Media Player. If you have configured Windows Media Player 
to automatically download codecs and the correct codec is available, 
then your file should play. You must be connected to the Internet to 
download the codec file.
My music files 
don’t appear in the 
Media Library.
Make sure you use Windows Media Player to add your music files to the 
Media Library.
Check that the Windows Media Player setting for Access rights of other 
applications is set to No access. It must be set to Read only or Full 
access for your music files to appear. Refer to Windows Media Player 
help for more information.
