Hi,

I don't think it's only the movem causing trouble. I did a little test now 
with playing a module using DSPMOD. Here are my observations:

* Sound is noisy (scratchy) about every third time the module is started

* Left and right channels are swapped almost every time the module is 
started

* Sometimes the left and right channels even swaps during playback of the 
module


Here is the player with the module (I did it just for test to be certain 
of left/right):

Just drop stereo.mod on dump.ttp
