Helloooo.

Are you using the same device to route the audio and video signals and its receiving and responding to some commands and not others? Or are you using two separate switching devices, and one works but the other doesn't? What are the devices, make and model? Do you have an ir emmitter with visible output, ie blink or test ir?

BTW, the most effective way to troubleshoot ir repeating sytems is to break the system down to its simplest form, one emiiter, one "sender", and one device, and add the additional elements (including long cable runs) one at a time until the system fails and identifies the proximate cause.

It is likely that the trouble is the long run of control cabling is picking up EMI/RFI along the way, increasing the signal to noise to the degree that some commands are undecipherable. Its the reason sheilded cabling is often used, and the path low voltage cabling is run is an important detail.

Xantech offers a detailed guide diagramming some common applications for ir repeating on their website if you would like to check your connections.

PS Complaining about the lack of FREE advice is IMO poor form. I certainly hope that you plan on contributing something worthwhile.
