I myself was wondering what programs i can use for the UX40/50, i tried omniremote, shockTV, Phillips pronto with the perfect remote add-on for clie... none worked to the best of MY ability, but im rather new to the whole thing. The UX40/50 series dont have EIR apparently, but even though the range would be extremely short id still like to have it, i can use it in my car and be neat for other things, anyone know where i can get the UX compatible program for non-enhanced infrared?
