I am looking for an ir transmitter/receiver to create macros (i.e. turn on tv, turn on cable, turn on receiver with a push of a button) for my HT equipment? I was looking at the Ocelot and USB-UIRT but am not sure if they will work considering my computer is in a different room than my HT equipment. Would I have to go with something like a Global Cache to make the 50+ feet? Also, what if I wanted to control the HT equipment from another room? For instance, I want to change the radio station from my porch (porch speakers are powered by my HT receiver).
