I bought this player to replace my aging Clip+, which has not had any problems with the MP3s I loaded onto the SD card (either stock firmware or RockBox). I used a new SD card in my new Sport and copied all the music from my Clip+ to my Sport. Now, randomly, I’ll sometimes have the player randomly stop playing music, display “File format not supported”, and I have to hard-reset the player to get it to play again.
The thing is, I can’t replicate the problem at all. I did a search in Windows Explorer for NOT name: *.mp3 and it came up with nothing. I then skipped through my entire library (eating up the better part of an hour…) from start to finish and not a single song threw the error.
Is anyone else experiencing this problem?
