Any help or thought about my RF problem is greatly appreciated...
Ok, here's the problem, I recently bought the RFX-6000 for using the RF function of my TSU6000. All components in my system is working well with the RF to IR except for one component, the RCA DTC-100/DirectTV Receiver.

When I switched back to using IR mode for the sat-rec component, the TSU6000 works fine as before. I noticed that it works every so often using RF mode; in RF mode, it seems to work once in every 10 times I try... It's frustrating because the rest of my system seems to be working fine. I've updated the firmware & reloaded my programs but nothing seems to work...

Btw, the buttons/component for the sat-rec is not alias to any other device.
