Thanks for the reply Gonk. While my wall was open, I installed two high-quality 5 meter HDMI cables, another "back-up" HDMI cable one(that came with my HDtivo), a SVIDEO wire,, a component video set, as well as RCA wires and five separate sets of speaker wire for the future. I have a total of 15 wires going from the rack area to behind the plasma, just to be safe. I even had a dedicated hospital grade surge supressor plug installed in the wall just for the Plasma.
As to switching, I use a universal remote with macros so I would rather have a direct connection. Also, the HDMI transmits sound which my wife may use when she merely is watching the news or a soap opera.
When everything arrives, I should be all set (though I will have to install the upgrade in the 990).
This forum is very informative.
