    I have an IR sensor and a connecting block set up so that I can control a bunch of equipment that I keep in a different room from my main setup. I am currently using IR emitters, placed on or near the device's sensor, which works fine (but not perfect).

    On some of my equipment, (namely my Integra Research RDC-7 pre-amp and my Scientific Atlanta 3100HD & 2200) there is an IR input on the back. I have attempted to use this direct input with 1/8" audio plugs (I have tried both mono and stereo), and nothing seems to work. Furthermore, I am trying to connect my TiVo's IR output directly to a cable box, which doesn't work.

    As far as the RDC-7 goes, neither the MAIN zone or ZONE 2 work at all. In earlier configurations that I have had (old apartment) ZONE 2 worked great.

    Any ideas?

    I can't help you with the direct inputs. However, I got more consistent (perfect?) results when I switched to a regulated power supply and covered the emitters with mouse shields (black electric tape will work). If you use the shields (or tape), you won't be able to point the remote directly at the device anymore.

    Unfortunately, I made these changes simultaneously, so I'm not sure which one provided the improvement. :b

    Good luck.
