Yes the answer is no as my tv only has component and I guess my new Oppo 970 does have HDMI. Okay I'm now looking at the back of the 990 so:

My DTivo has only S-Video so I should run it into Video 1 In (S-Video) and the optical output into Optical 1 In.

My Zenith HDV-420 OTA tuner has component outs so they should run into Component 2 In and the optical to Optical 2 In. Currently I have a couple of different outputs I'm running out of the Zenith but I can't remember why. I'm running analog R/L for audio since I never had any digital cables but I'm also running another R/L analog audio and composite video out from 480i output although I don't know why. Maybe I ran more cables than I needed to.

My Dvd should run Component out to Dvd Component In.Then run optical out into optical in. Do I just pick any optical input not in use since there is not a designated one for Dvd?

I understand about hooking up the vcr. Can you verify that I'm understanding so far what I'm doing? I have 3 optical cables on order from Outlaw, one for the Oppo, one for the Tivo and one for the Zenith so I guess I need them before I can do much.
