I tried adding the 6131, but it wouldn't respond to any power button presses after the code download. Since the 6131 is very similar to the 6141, I tried downloading the codes for the 6141. With those codes, the power button now works though I have to wait several seconds before pressing it again to get the device to turn on. However, while the power button works, none of the other buttons work (channel change, guide, info, etc....). Has anyone had success getting the 6131 to behave properly with the X1?
