For whatever reason, the symptoms you describe are best explained as the SXRD incorrectly using the SDTV color space math internally for YCbCr to RGB conversion when connected to the D2.
I'm not sure why it would do that.
But this explains why the picture corrects itself when you set the D2 to either SDTV output of YCbCr or to RGB output. When the D2 is set to SDTV color space output of YCbCr it is converting the YCbCr to that color space -- which apparently matches what your SXRD wants.
When you set the D2 to RGB output it is doing the conversion to RGB itself -- and doing it correctly for an HDTV display. Since the data is already arriving as RGB the SXRD has no math to do so it doesn't screw it up.
So again, the most likely problem here is that somehow you have managed to set the SXRD to expect that YCbCr is arriving in the SDTV color space even at HDTV resolutions.
If the color space math is right, and there are no other errors in the color decoder in your display, then the "best" Color and Tint settings when viewed through the blue filter will also be close to the "best" Color and Tint settings when viewed through the green filter. The red filter measurements may be further afield due to the common problem of "red push" found in some displays. If you've got it wrong, green "push" or green "depression" is pretty evident -- something like 15% as measured by the Avia color decoder test as I recall.
Thanx again Bob,, You are the awesome
Finally solved what was happening, and very, very, happy to say that the D2 is decoding inputs correct...
Like you suggested, I threw on the test patterns from the D2 to the SXRD, went to the colour bars section, and looked thru my green, blue, red filters..
Here is what happened..
thru blue filter, all looked same shade (therefore set correct)..
thru red filter, same, all same shades..
Green filter, shades were NOT same...
Checked my D2 settings.. Was set to HDTV and YCB 4:4:4...
SXRD was detecting the 701 matrix (sending a 1080p singnal to SXRD)..
Chaged output of D2 to YCB 2:2:2, and same error with green..
Then tried the RGB output, with HDTV colour, and WOW, green shades dialed in perfect with internal test patterns..
So, Went back to all my sources, from Oppo (480i, YCB 4:4:4 setting on player - D2 detected SDTV signal colour space), and GREEN PERFECT..
So far so good..
Toshiba HD-DVD A2 player, set to 1080i, GREEN PERFECT..
PS3 (1080p setting), same, GREEN NOW PERFECT...
To sum things up, looks like my SXRD likes the RGB output from D2, as compared to any of the YCB settings..
Now I can see movies with correct colour tones!!
This now brings up the question,,,, Why when using Oppo direct to T.V. using the YCB 4:4:4 setting, green levels correct, but when going thru D2 with same settings, I have to use the RGB setting on D2??
For fun I tried the RGB setting on Oppo, and no colour change in green (when going into D2)..
Thanx so much again for all you help Bob...
