I just got a new TV and there wasn't any space to put my HDVR2 in line of sight from where you sit. [I have a built in TV shelf above the fireplace, flanked by some bookcases.] So aiming the remote at the DTivo unit is not always successful. I bought an IR emitter cable similar to this one pictured and plugged it into the IR control out located on the back of the unit. It does not seem to be doing anything. I did a reset and also tried this cable on a SIR-S4040R. Either the port is disabled or this is the wrong kind of cable. What am I doing wrong? Elsewhere on this forum and on the net, when IR blasters are mentioned they talk about using a remote to control multiple devices and/or items in another room. I consider this a pretty low tech scenario, so those boxes for $35 and up are not what I had in mind. I could move the Dtivo if that is the only answer, but that would mean fishing coax and a bunch of AV cables through a little hole in the drywall. It would be time consuming and frustrating, also I have no doubt the hole would have to be made larger.
