Thank you for that command. That was a lifesaver. Is that in the FAQ?

Ok details on the file 131203130 bytes (aprox 12min)
format fs1411 which I believe means 44.1kHz 16bit stereo. File is titled CDTestSignal and all other fields are empty. This created an item in the empeg playlist tree that looks like just a musical note symbol with no name and the track below it (likely irrelevent).

I am replaying the wav file now. The lockup happened in my car within a few ms of a restart (I pulled the player to fix a sticking button). It was definitely playing that one track because every reboot it would make it to displaying the track name before freezing I could also sometimes make 1 button press take effect before the freeze.

HAH...I played the file 7:12 with no problems. Well past where the problem occured then repeated the problem by pulling power and re-powering. Want anything more?

Ack didn't know about the looping thing. I spent hours last night trying to find a long clean pink noise .wav file.
