I really appreciate the help and advice. I'm starting with the Oppo running via DVI through the 990 to the TV and after a brief test, it looks better than it did with Component. My STB is still component through the 990 since (duh) I discovered I was missing the HDMI/DVI cable to connect the STB to the 990 (I was sure I had one . . .). I'll post results after I've had a little time to compare.
