Im not sure what you mean when you wrote " Have you tried punching through the directional keys from the pioneer device to the pioneer device?" . I attempted to have each directional keys taught the commands. CCP says the signal was capture but yet wont function as it should. It wont scroll down, left or otherwise but everything else works. If anyone has been able to use directional keys of a pioneer sc when the net functions are used, please let me know. CCP cant seem to figure it out.

As you have suggested, I used my old harmony one remote to learn the commands and subsequently, have my mx5000 do the same. It still doesnt work. Im puzzled...thanks for your feedback
