I was thinking along the same lines as you appear to be - let the DVI signals run through the 990 for the HT room, and let the component signals run to the old receiver which could then power the workout and party rooms and feed the 27" LCD. As an added benefit (which can't be done with most receivers and processors; the 990 is like most systems in that the second zone is limited to s-video or composite video), you can then control the two HD displays' sources independently (watch a movie on the Oppo in the HT room and watch TV in the workout room) or tie them together (listen to music from the same source in all three spaces at once).
