Well, technically speaking, any signal coming out of an RF Modulator (the Coax Output of a cable box or video game) shouldn't be stereo, it should be mono (at least that's the way they used to work in the days of VHS and video games from the N64 era and before.)
So unless they've changed RF Modulators since then so that they output stereo audio now, then there shouldn't be stereo audio coming out of the coaxial output of your mini-cable box...
