If you only have one input in your stereo, then you can only hook one into your stereo, I would pick dvd, then if you want to listen to D* on your stereo, turn on your VCR/DVD player. Now if you have two free audio inputs on your stereo, then put them both in and switch back and forth, make sure red goes to red, and white goes to white.
Take the Satellite out coax and put into the VCR/DVD combo, then you could record shows on your VCR, then take the coax from VCR/DVD player into the T.V. input.
Keep the T.V. on whatever input channel you have(3 or 4) and the same with your VCR/DVD player. Then you just use the D* remote to change stations.
I don't know if this will work without seeing your system, but it might be a start.
