I just recently spent considerable time trying to do the same thing  
you are doing without success but the problem is NOT the IguanaIR. It  
works great.

The problem is that the IR receivers are so sensitive that even the  
slightest reflection off of not-so-nearby objects is sufficient to  
activate any nearby STB using the same code set. This, combined with  
the fact that those sensitive IR receivers can be completely saturated  
by emitters placed directly on them, leads to bizarre effects such  
emitters activating nearby boxes but not the boxes they are attached  
to. Etc.

If the STB's can be set to different code sets, then you can easily  
control all of them with a single emitter placed a reasonable distance  
away. Or, if your STB's have jacks for remote IR receivers you can  
workup something foolproof using optoisolators. Or, some types of  
STB's have an alternate, direct method of channel changing such as a  
serial or FireWire port.

Otherwise, you could try attenuating the signal reaching the STB's IR  
receivers with something like multiple layers of white copy paper. If  
you come up with something that works extremely well, do pass it on!
