Wow...now I'm really starting to wonder if this IguanaIR unit isn't
just plain bad. I just dug out an old remote from a Phillips DVD
player I had. That works with my MCE USB receiver and the rc-6
protocol just fine, but again, gets absolutely nothing from using the
IguanaIR with rc-6. That sort of rules out any issue with NEC
specifically. I hope someone can answer my question as to whether
those are supposed to light up.

Thanks
Tom
