Hi William, 

Below is the connection of the DMR EH75 to the TV and Cable Box. If your Spectrum Cable Box is only using an HDMI  (Digital signal)  the DMR EH75V model only support Analog signal and will not work. Also,  you won't be able to feed any HD signals from the STB to the DVDR.

If your TV and Spectrum box has the option to use the RCA then you can proceed by following the connection diagram below. You may try an adapter like an AV RCA (input) to HDMI (output)  adapter to convert the analog to digital signal or the last option is to use a new digital recorder equipment that supports digital recording.
