Hey!
I got it working! The NEO does work with the showstopper! I had to mess and mess with it but I got it. Here's what I did;

I held down the button on the replay remote for a few secs. then I het the button on the Neo that I wanted to learn. This worked about 70% of the time. For the more stuborn ones I did this;

Move the Neo to the edge of the table with the ir window looking out off the edge, then take your replay remote and lower it or raise it and point it at the Neo ir signal.

Hope this helps.

thanks,
DAO
