I use a DIY universal remote made from an Arduino using the IRremote library that allows me to send a code like:

4550,4450,650,1600,650,1600,650,1600,650,500,600,500,650,500,600,500,650,500,650,1600,600,1650,600,1650,600,500,650,500,600,550,600,500,650,500,600,500,650,1600,650,500,600,500,650,500,600,500,650,500,650,500,600,1600,650,500,650,1600,650,1600,600,1650,600,1650,600,1650,600,1600,650

to an infrared emitter. That code would power off my Samsun TV. I have that process setup for my TV, Insignia receiver, and my Mac Mini and it works great on all of them. I also have a DirecTV model HR24-100 that uses a DirectTV remote RC65X which I can not get to work. The IRremote library for the Arduino also has a process for decoding infrared signals which I used on all of the devices. The DirecTV buttons get decoded and seem to intermittently work and then will stop all together. Decoding the same buttons on the DirecTV remote will then produce a different code.

Does anybody have any insight on why the DirecTV remote will produce different output over time?

There is extra signal included with each button press on a directv remote, if you want a cleaner signal to decode for you process, do the following on the remote, then capture the signals:

1. dtv
2. press and hold MUTE & SELECT, wait for two blinks, release
3. enter 9 6 3
4. press CH DOWN

WOW! Thank you edmund! Have been pulling my hair out with this.

Can you elaborate on what the extra signal is?

Previous remotes only transmitted the remote ID with each command, the newer x series has two-way communication with newer receivers. During remote programming, receivers can put upgraded codes not already in the remotes memory, its not permanent, one reset and they are gone. see this press release:

Thanks for the link. I had no idea DirecTV had implemented that.

Is there anything like this page on Remote Central that might have the codes I am looking for?

you might do a search in discrete hunter or rs-232 forums here on RC.
