As I understand it, you want to try to use both the component and DVI video connections of the DVD input for different components. I think that is possible (you'd want to set the DVD input's video to component), but you may have to turn off the DVI source to get the component input. The setup for that input is going to want to have a single digital input assigned to it (specified as coax 1, 2, or 3 or optical 1, 2, or 3 - assuming you won't be using one of the front digital inputs). That means the sound from the second source (the Sony jukebox) wouldn't be active at the DVD input. One trick that could work for what you are trying to do (speaking as someone who doesn't have a 1070 or 970, so I can't try it)... I'm going to assume that you'll use coaxial from the DVD player and optical from the jukebox. Connect the audio from the DVD player to coaxial1 and the audio from the jukebox to optical1. Assign coaxial1 to the DVD input and optical1 to the AUX input (an audio-only input). If you switch to the DVD input, the 1070 will make the DVD video input active (which means the video switching will start using the DVD video source). If you then switched to the AUX input, the video would stay with the DVD and the audio would come from AUX. It's a little quirky and I can't try it out, but it has potential. I suspect that the 1070 would be a very rewarding upgrade from a Denon 2105.
