Hi: Can some one help?

I've decided to use my trusty Ipaq 5450 (with updated OS 4.20.1081- 2003) as a home theatre remote. Nevo is loaded and I can learn IR codes and use Nevo to control items. Clunky.

So I have been learning Pronto (but using Tonto) and am ready to import my IR codes from my remotes via the Ipaq into Tonto. I have tried learning IR codes from within Total Remote and Net Remote. Both show that codes have been learned. I can see that codes exist when I open the file in Tonto, but when I try to use the codes from either program on the Ipaq, they will not transmit.

Have I missed something really basic here?

Cheers Rob
