1. All components work FLAWLESSLY when aiming the pronto directly at the components.

2. Three Denon components (AV Receiver, DVD and CD Player) as well as a Pioneer Elite BluRay player work with the emitters stuck over their IR Receivers.

3. I have tried trouble shooting by swapping emitters and emitter ports from the distribution block. That doesn't seem to be the problem. The problem is only with the two components I mentioned, and it happens with any emitters running off of any emitter ports.

4. Tried for 3 hours without sucess to find a suitable place for the emitters for this component. The TT12 never worked at all. The HR22 worked intermittently if I had the TSU9400 at a very steep angle to the IR receiver and within 3 feet, and had something over the front of the emitter and the HR22 to ensure there was no bleed through (such as a t-shirt or my hand).
