I use the build in music player on my Dinc to listen to mp3s. I mainly listen to audio books. Here is my problem: some mp3s restart themselves at the beginning after the Dinc has been left idle for a while (several hours). Why do some mp3s do that? I cannot figure it out. I have mp3s of this particular book that are around 35 to 40 minutes in length and when I paused the player last night and woke up today to simply resume listening, it immediately restarted at the beginning. Any ideas? I think it is a problem with the mp3 itself as this very thing used to happen with my enV Touch from time to time with certain mp3s. Any ideas?
