Thanks for your input.
The Oppo is a Vudu enabled device and is the source for streaming. Exactly how that works regarding the de-compression codec from source over the net and the format being sent to the Integra, I have no idea? But, I have tried using 'direct' with both the Oppo and Integra which means any necessary processing is being performed at the DILA and it looks pretty good. Streaming has come a long way.
Occasionally, I do watch DVDs and using 'direct' to the DILA doesn't always work. Sometimes the aspect ratio of the projected image is wrong. In this case, I set the Integra to 1080p out and it works good.
I usually believe the newest device is better than the older at performing the processing. The Oppo is new, the DILA is next and the Integra is circa '08. I can test various combinations of processing and compare, but was wondering if there is a suggested device/component and/or order in which the video signal should be processed as it passes from source to image.
If the DILA is suggested for processing, that is how I normally set with both the DILA and Integra in 'direct' or 'through'.
