So I have an HR24 connected up to an HDMI splitter, so I can watch at multiple locations throughout my house. Accordingly, I have four remotes I use to control that one box via RF. Until a couple days ago, all four worked fine, from all corners of my house. Yesterday, I started having to hit a few buttons multiple times before they would take, and today I can't control the box from anywhere except within maybe 6 feet of the box. I know its not the remotes themselves, because I checked all four - they all work when close to the box, and none of them work from across the room or in other rooms, and they all used to work in exactly those places a week ago. (I swapped out the batteries in a couple of them anyway, just to be sure.) Any clues as to what might be happening? My first guess is some kind of interference; I did get a second HR24 box a few days ago, which sits right next to the HR24 - but I control it via IR (so I can hook it up to a slingbox). This new HR24 replaced an HR21 that was failing, and was hooked up the same way, but I did move a few things around in my setup. Maybe there's now some kind of weird signal valley with all the wires and stuff back there? Or maybe somebody nearby has started blasting radio waves or something. Still, the most likely scenario seems to me to be an issue with my HR24. I did a red button reboot and a yank-the-power-cord reboot, neither of which solved the problem. Anybody have any ideas how I might fix this? As I understand it, there isn't an external RF antenna jack on the HR24s, so I don't know how to boost the signal.
