Ossocao,

do you have any devices, such as a PVR, that requires fast navigation? If so does it all work very fast if you press your buttons over and over again? Example such as I have mentioned with navigating the guide.

Reason I ask it this way is because on my DVD, VCR, Reciever, TV it seems great. But with my PVR and Xbox 360 where there is menu navigation it is sllllllooooowwwww.

The IR device on my HTPC definitly is not receiving the info as quick as my other remote sends. I am able to tell since the IR Receiver I have going to the PC has a green light when it gets the signal.
