I'm waiting for the delivery of my RF stuff today. What nudged me over the line is a peculiar problem I have: I have a Pioneer DVD jukebox that responds to exactly the same IR codes as my Pioneer DVD/LD player. My theory is that if I feed the codes directly to the individual devices through the little emitters I can avoid having one device spring into action from commands intended for the other. (If you think this sounds like an excessive response to a trivial problem, I can only agree.)
