I am trying to intergrate a media center pc into a home theater system, controlled by an mx3000. The codes control the media center pc, but the directional buttons are only responding to the first touch. A second touch won't work for a few minutes, then you can hit it again. Going back and forth the original pc remote does not have this problem. Anybody have a reason why? It learns the code, but can't repeat it in succession. Do the pc remotes have some kind of sequential coding that changes for scrolling? The only solution I can come up with is to have the customer use 2 remotes...(yuck!). Any help would be great. Thanks.
