I have been having an issue when I copy music on an SD card and attempt to playback on my system. After playback of a song there is a second file which has a dot in front of it which the system attempts to play. The system then skips the song and then attempts to play the next active track. An example: If I am playing the song go, the next track will display as .go and the system will skip it and go to the next active track. Does anyone have a solution for this?
