Say that I'm watching ABC's Modern Family. Here in Phoenix, AZ- ABC and that show transmit in 720p. I have my Tivo Roamio in Native Output mode which is connected to my 103D. On my 103D I can upconvert this show in 1080p or 720p. What I'm trying to say is that the 720p output resolution of the 103d shows slightly better PQ compared to the 1080p. Same thing if I match a 1080i native tivo channel with the 1080i output resolution of the 103D instead of the 103D's 1080p.
Hope this makes sense now. I'm trying to understand why that is. Maybe it's because upconverting to 1080p involves more processing thereby losing slightly less detail because of it?
This is almost certainly a setup error in your TV.
Some TVs use alternate settings when fed 1080p instead of 1080i or 720p. (Some TVs also have bugs that alter the display for no good reason for 1080p/24 input vs. 1080p/60 input -- so if set to do 1080p/24 correctly, and with 1080p/60 now being fed (given the Tivo source), the settings may be wrong.)
To check this, use a calibration disc (e.g. Spears & Munsil v2, Blu-ray) in the OPPO and compare with the OPPO set to explicit 1080i output resolution vs. 1080p. You can also check 1080p/24 vs. 1080p/60 (Video Setup > 1080p/24 Output > AUTO vs. OFF).
You could also check with the OPPO set to explicit 720p output resolution, but you'll likely get confused by the loss of resolution inherent in down-scaling the 1080p charts to 720p for output. DVE HD Basics, Blu-ray, has a set of 720p charts if you want to double check 720p content output as either 720p or 1080p from the OPPO.
In all cases the Picture Adjustment controls in the 103D should be left at their Factory Default (0) values -- in particular, leave Darbee OFF while checking such stuff. Any adjustments needed should be made using the controls in your TV.
When viewing the TIVO through the OPPO, first of all, set the TIVO to output YCbCr 4:4:4. NOT YCbCr 4:2:2 or RGB.
Next use the Info button on the OPPO to verify what is coming in from the TIVO (top line) and what the OPPO is sending out on its HDMI outputs. Double check that what's happening is what you think is happening.
