Not all players play all formats. There are a number of different recording formats and disc types. If it's recorded in MP3 format, only certain players will play that. I would expect all like GM players to work the same. If you purchase an aftermarket player, it will tell you what formats it will play. You might want to check also that sometimes it's just a matter of closing the format when you record it.
