I am trying to download a CD on to my Samsung R1 player. I have downloaded the CD on to the computer and transferred it to the Samsung R1 player but cannot open the files on the player can anyone assist

MP3 players can only play music files in mp3 file format.You need to convert your CDs to mp3 music files onto your computer ordownload them from the Internet and then copy them to your MP3 player.
You can do this using Windows Media player and Rip the CDs - Media Player willcreate a MP3 music file for each music track.
