Are any of your other sources (specifically the satellite or DVD recorder) capable of component video output? If they are, you may want to connect them to the 990 that way and replace the s-video monitor cable with a component monitor cable. That will give you better picture quality from those component-capable sources, and will still let you see the s-video and composite video sources over the component output. As obie_fl says, you'll still need to switch the HDTV's input between analog (s-video or component) and digital (DVI/HDMI).
