You may want to read my earlier thread, re: ready to return the sucker. I had IR transmission distance problems with my remote. It could only xmit about 8 feet to my Pioneer Elite TV and to a stand alone IR Sensor unit which runs my TiVo. Other people thought that I may have a defective unit, but I didn't bother to return it since I switched to using RF transmission with the IRF-6 instead. Now everything is working fine.
