voice recording sputters out.
 

I have a glacier. and the main reason I purchased it, (unlike the rest of you) was to use it as a voice recorder. Okay I record lectures and then when I get home I pull the voice file up on my pc and make a copy or just play it from the voice file from the glacier. Well either way I do it. It will play fine (actually very well) for about 5-10-15 minute intervals and then it will sputter out. Ive found that if I pause it and rewind back maybe 5sec and press play it will play fine for another 5-10-15 min and the sputter again and I repeat the process. does anybody know whats going on here???
