Tom while I can't comment on the setup of DMP-1 the 990 is a very simple setup. However I think a better question would be is how do I make the home theater easy for my wife to use?

That is where a universal remote comes in, I personaly use a Harmony 880 so all my wife has to do is push the watch DVD button and insert a DVD or push the Watch TV button and she can watch cable. The simpler you keep it for them the more they will enjoy your hobby with you.
