What I think Gonk is saying is that the DVI inputs are only connected to the DVI outputs on the 990. The 990 doesn't take DVI inputs and convert them to a component/s-Video output. If you get a new HD-DVR you will have to use its component outputs to feed the 990 until you get a new TV with HDMI input. At that point you could use the DVI to feed your video signal directly to the TV. You will also have to run the audio channels to the 990 also. I use the Optical output of my Directv HD receiver as the audio input to my 990 and the HDMI out from it to the 990 DVI 1 then on to the TV. I use cables from Bluejeans to accomplish the HDMI to DVI swap. I also input my DVD player into the DVI 2 position and then to the TV. In both cases I use the optical output for the audio side input to the 990.
