Hi, I have an original FLIRC that I have updated to the latest firmware and works great when directly hitting it with my windows MCE remote.
When I go through my Xantech repeater, I get about 95% failure rate. Like 1 press goes through every 20 presses. All other devices like receiver and cable box all work.
I found the other thread that suggested electrical tape on it, which did not help and no presses worked then. Unsure what to try next.
