Query: Poor anti-skip behavior

I use my RioVolt SP90 to listen to music and audio tapes while walking for exercise. I have found to be quite undesireable for this function, due primarily to the short 120 second anti-skip buffer. Invariably, withing 15-20 minutes of starting my walk, it runs out of buffer and stops playing. From then on, it plays a few seconds, then stops for as much as a minute before resuming. Very frustrating. No matter how I carry it, I cannot avoid the severe interruptions in play. I guess it would be an okay player if you have it setting on a desktop or something.
