I already know that I will not be using the Oppo bdp 83 for video processing or audio decoding.

I know that I will be using Source Direct via HDMI and setting the Oppo up to do as little video processing as possible in order to leave this to a downstream processor.

I also know that I will be bitstreaming the audio via HDMI, leaving all of the decoding, speaker set-up, etc. to my surround processor.

I also know that I will only be using the Oppo bdp 83 for DVD and Blu-Ray and will not be using the Oppo bdp 83 for CD, DVD-A, SACD, or for any other type of software.

So, my question is -- has anyone who is using the Oppo bdp 83 in this fashion, as a digital transport for DVD and blu-ray only, had any difficulties?

Or are all of the people who are reporting difficulties using the Oppo to decode audio, set-up speakers, process video, or using it for CD, SACD, DVD-A, or other types of video besides DVD and blu-ray?

To be clear -- I want to hear whether anyone who is using Source Direct for video and Bitstreaming audio in digital through HDMI and limiting usage to DVD and blu-ray only has experienced any difficulty.

Using extra bits for video processing for scaling helps and so does 10bit vs 8bit output. However, that is a lot more than just switching between YCbCr 4:4:4, 4:2:2 or RGB. To figure out why things work as seen more details on each end need to be known, e.g. when set to Auto, what was the display seeing? Is it possible RGB was being sent and when the display sees RGB it interprets is at PC video levels as opposed to studio video levels. Is the Oppo somehow output PC levels? (I would hope you'd have to force it to do that).

I changed the color space from 'auto' to '4:2:2'. In both cases 'deep color' was turned off. The difference in quality was stunning.
I then tried 4:4:4 and the quality was still stunning.

I then tried 4:4:4 and the quality was still stunning. There is a marked improvement between 'auto' and the other two settings. It is a night-and-day difference, not some minor change due to calibration being off.

For the uninitiated, this is what's known as "technical talk". It must be, as this is a "technical talk only" forum.

Is anyone aware of a forum that discusses the BDP-83 that is modded?

It's either 4:4:4 (default selection for AUTO under most conditions) or 4:2:2. Both of which you claim to be stunning.

There was no change in the calibration, and no apparent difference in SD-DVD quality.

The next test was changing the color space. With a disk playing (Last of the Mohicans) I changed the color space from 'auto' to '4:2:2'. In both cases 'deep color' was turned off. The difference in quality was stunning.
I then tried 4:4:4 and the quality was still stunning. There is a marked improvement between 'auto' and the other two settings. It is a night-and-day difference, not some minor change due to calibration being off.

I then ran through the calibration settings, again using the S&M disk and the AVSHD disk. The calibration was spot-on, nothing changed.

I'm much happier with Oppo's SD-DVD quality. I may have something set incorrectly in the receiver or panel, but if I do it's a common mistake. Changing the color space to anything but 'auto' corrected it.

I suggest that jkozlow3 with his 106" screen try changing the color space setting. He might be able to watch an SD-DVD without zooming.

Any time you have a display that can accept 4:2:2, you should use 4:2:2. 4:2:2 is the closest to what is on a BD so it is more of a native output. If the player outputs RGB, it must first convert from 4:2:2 to RGB. Your display must then convert back to 4:2:2 for processing. And then before the image is displayed on screen the signal must be converted back to RGB.

By using 4:2:2 you save on two digital conversions which will provide a much more precise image. Also, the color will be much better with 4:2:2 because of 10 bit verses the 8 bit of RGB or 4:4:4.

I would also suggest leaving the deep color turned off.

I don't know why, and right now I don't care. What I do care about is the quality is excellent after I made the change from 'auto'.

Again, it is a marked difference, not subtle at all. There are two other people that have admitted to the same experience, so it is not just my eyes and/or set up.

I am willing to believe the problem is in the HDMI handshake. I am just suggesting that other people try setting the color space instead of leaving it on 'auto'.

I am recalibrating after every change.

Is deep color artificially up-sampling the color space to 36 bit? Does it make a difference in what your display can handle in bits as to which color space you should select?

i know others have had a similar problem, but has anybody figured out how to correct this?

It has a coax and optical input in with stereo analog out. I was thinking of picking one up to hop up the 83 for CDs. The review I read was very good. http://www.avguide.com/blog/the-little-dac-could Comments welcome.
