I knew about the VBR problem (the vast majority of my files are VBR), I just thought that the 'not enough time to write before there isn't enough power left' problem gave exactly the same symptoms. I thought it would just lose it's position within the track it was playing. I wasn't aware that it would forget which track it was on. I'm surprised the player doesn't store the FID of the current track after a few seconds of playing it. Anyway, it's only happened to me once in almost a year so it isn't a major hassle.
