There are occasional spontaneous reboots as well. The glitching I'm pretty sure is not mp3 based because I've never heard the glitches on the mp3s on my computer, plus if I rewind and try to hear the glitch again, sometimes it's not there, sometimes it's different sounding, etc.. The other problem is the locking up issue - it's only happened a handful of times (maybe 3 or 4 on my 2000 mile trip) but it just hangs in the middle of a song or when I attempt to change songs. When I reboot the unit, it will take a very long time (~20 seconds?) on the 'Building Music Databases' section. Do I have a hardware problem here?
