I've read other reports of sporadic buffering problems when the device is connected to a computer. My theory is that the computer's file system requests when it scans the device sometimes cause that to happen. If you're seeing this when the device is unplugged, and with wifi and bluetooth also off, you should contact iRiver support and see about sending it in for repair/replacement.
Here's the number for their customer service line for North America, located in California: (949) 336-4535
Yep I've only experienced it when it's unplugged, usually when using it out on the streets or when commuting. I'm located in Hong Kong and a wild guess would be due to the hot weather + prolonged usage? The device does run pretty warm and maybe the high temperature just pushed it over the edge....I have no idea. Will visit the customer support soon, it hasn't been happening the past few days....
