Hi Folks, I'm just getting back to using my NH600D after trying a phone/mp3 combo. Now that I have loaded a few HI-MD disks half way or so, some tracks are are distorting in a way that I would call stuttering, since it rapidly repeats a half second or so, accompanied by a sputtering noise and then moves on. What's the deal? Is my player going out? Does the head(s?) need cleaning or are my disks bad? This has happened on more than one disk, and is usually at least half way through the disk. I have used the same laptop with SonicStage 3.4 to upload the suspect tracks. Any clues? TIYCH
