NYGIANT's problem is unusual - I'm using my 990's DVI switching with an Oppo without any difficulty, and would expect you to be able to get it up and running just fine. Just remember to run at the very least a composite video cable from the 990's monitor out to the TV for access to the menus. If you will be using sources other than your cable and DVD that can make use of component video, a component connection from the 990 will also give you access to the menus.
