I have two Dish 311 receivers. Rather than deal with an IR blaster that either requires an ugly LED attached to the two units, or a blaster that is subject to interference, I made a really cheap (about $15) hardware modification that allows me to make a hardwired connection directly from the 311's board to a small interface board that sits inside my HTPC. The interface board is connected to a serial header on the PC's motherboard.I would be interested. Sounds like it will still require lirc or something similar though.
This hack involves a handful of components, as well as opening the Dish receiver and breaking one IR receiver lead. When the Dish->PC cable is plugged-into the back of the Dish receiver, the regular remote is disabled; when it is unplugged, the receiver operates with the remote.
This change will void your warranty, and should also not be performed on leased equipment.
I have only tried it on a Dish 311, but there's really no reason this same circuit shouldn't work with other IR-based equipment that lacks a real, hardwired interface. If there's enough interest, I'll do a writeup and post the URL here.
