I've used the mini out, and now I wish I could remember what show it was for (so I could correct it). In doing some testing with my Aerco this weekend, I realized that the mini out is wired backwards for the typical stereo minijack -- left and right channel are swapped (meaning technically, the tip is the right signal and ring is the left signal on the jack).
At least it is on my Aerco, not sure if this is the standard Jerry used for all the Aerco's.
