More likely, there is IR interference. I tried the RR200 and had a problem with it working in conjunction with a wired remote extender. They interferred with each other. Originally I had the IR emitter for both the wired remote and the RR200 next to the TiVo. Having the two IR emitters next to each other in the basement just confused it. What I ended up doing is have the RR200 transmitter next to the wired receiver that then sent the signal to the TiVo in the basement. Now everything works just fine now, until the little battery gets low. The newer RR300 has a rechargeable battery, I believe.
