Hello,
For a customer I have set up an RTI T2+ learning remote to operate all of his home theater components plus his Hewlett Packard z545 Media System PC. Everything is fine except for the learned operation of the PC.
The PC comes with an RF keyboard and a small IR remote. Both original remotes work perfectly. I learned the codes from the small IR remote and encountered the following results:
Each learned command will execute perfectly ONE TIME only. For example, channel up works 1 time but not a 2nd or 3rd or 4th time IN A ROW. It will not work again until you have executed a different command and then gone back to channel up in which case it will work 1 time and only 1 time again. This is true for all commands.
I have looked for an IR setting to change in the PC's control panel and in the settings for the media software itself without any success. Request for help from HP has so far not solved the problem.
I had a similar problem with a Sony Media Center about 9 months ago in which case a change of a PC setting made for useable IR commands. Unfortunately someone else found and changed the setting and I did not note what the setting was. The Sony PC used the same Media software (from microsoft I believe).

Fellow propeller heads:
I'm disappointed that nobody here could explain the situation to me before Hewlett Packard e-mail assistance did. Oh Well.
Here is the solution courtesy of Henry from Hewlett Packard:
Disable the default IR "debounce" feature found on the HP media system. Do this by modifying a single registry key as follows:
Start Menu>Run>type REGEDIT, press ENTER. Navigate to the appropriate key listed below and change the EnableDebounce value from 1 (its default value) to 0.
Key location: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\HidIr\Remotes\745a17a0-74d3-11d0-b6fe-00a0c90f57da
Henry said that "The Media Center remote has two sets of codes that alternate with each button press, using a bit flipping technique. This method is used so that a single key press isn't accidentally received twice by the computer and is referred to as debounce."
Another solution exists but the one described above is the obvious way to go. Sony Media Centers have a similar situation if not the exact same deal.
