in general it is always good to upload your IR and RM files to the diagnostic areas and post links when you are asking for help. It's very difficult to guess as to what is going on without looking into what you have done
We need to see the files to figure out what is going on. I have a couple of guesses, but if I had the upgrade, and the IR file I could see if my guesses are correct or not.
Paul, I think its odd that 0,4,5,6 all have the same hex. Do you have the RM file for this? I'd like to make sure the output matches the settings you are choosing in RM.
I've tried uploading to my Comcast 1067A and then used CaptureIR to verify the ir output. It seems to output exactly what it is supposed to. See screen capture:
I haven't seen 1067a support in KM either. I really wish the remote was supported by km, because I am familiar with the way KM works. I think trying to use an upgrade for another remote might be the cause of your problems.
