Since you have the 970, you probably want to try using the digital coaxial audio cable to connect the cable box to the 970 (use any one of the three coaxial digital inputs). You'll also use the yellow video output (composite video). Both of these need to use a cable rated for 75ohms (a few examples include Outlaw's PSC and Blue Jeans Cable's identically-made but differently color-coded composite and coaxial digital cables) - a typical analog audio cable is not recommended. Ignore the connection for the VCR, and since you have the digital audio output you can ignore the red/white TV output as well.
