I recently changed service providers from a satellite service to a cable service. I am able to control the cable box with the 975 remote (found two codes which work) but when I enable punch-through volume the remote controls the cable box volume, not the 975 volume. I have tried both cable box codes, no luck This worked with no problems with the satellite service. The cable service is Spectrum.

I found the problem. There was a change in procedure between the version 1 and version 2 owner's manual.
