First time poster, seen the thread and tried to get an answer from the 500 plus pages but didn't see any.I've had my x3 for about 6 weeks now and it has recently started to shows signs of a fault. I have a mixture of flac/mp3 etc on the player and have a lot of mp3 DJ mixes on it. These mixes would be 1-2 hours long and played fine until a few days ago. Now, when I go to fast forward parts of the mix, the fast forward mechanism appears faulty. For example, if I want to fast forward to 40 minutes in and keep the buttom held until the 40 minute mark and then press play I expect the 40 minute track to play, but the song playing would only be about 5-6 minutes into the mix. I have tried this on numerous mixes, on a different TF card, internal and external storage. I am running FW 2.1 at present. I've tried reformatting via the X3 itself or with the PC, playing various formats but the problem still exists. Any clues what to do?
