John,
I have been through a dozen or so T2's w/ no signs of trouble. It seems the IRF-6 does not execute the commands exactly as the T2 does in ir however. One needs to be particularly careful w/ the timing of macros when issued by the IRF-6 that execute perfectly on the T2 alone. I also had a bit of trouble issuing commands to an EAD TheaterMaster Sinature Classic through the IRF-6 that went fine on the T2 alone. That being said, tech support at RTI (and a little persistance) has been able to overcome any difficulty I ran into. It ain't Crestron (a product with which I have never had an RF interferance issue), but it doesn't cost that much either.
