Gonk, you are exactly right - sorry for the delay in responding.

I already had auto polling disabled, but I stood and looked at the front panel and the display switches back to default every time a song stops and resyncs when the next one starts.

Now I just have to figure out what to tell them to do to keep that from happening. I don't know if they have control over the "blanking" of the optical channel between songs in their software or not - if they do maybe they can tweak the threshhold up a bit...
