Hm, it sounded awful similar to the wav problems, but on the other hand, I can't seem to replicate it here in front of my computer, and my car does have some vibration issues right now... I'll see if stopping the car helps next time. Oh, one more thing - rebooting the player would help, but it took 3 or more reboots to get it to work; the first couple reboots were very slow, and would get stuck on "loading visualizations". I'll move the Palm unit over from engine datalogging to watch the serial port on the Empeg, maybe that'll show up some clues too.

Thanks.
