I'm looking for feedback on this - Perhaps Jack, you may have an insight.Its hard to know the culprit. I've tried to narrow down the sole source of the noise, which I should describe in more detail.
First a look at my viewing system:
Sony KDS-R70XBR2
Dishnet DVRVIP622
top-of-line HDMI cable from Monster
Denon DVD-3910Those of you familiar with SXRD technology know it to be capable of incredible detail. The only problem that irks me is 'movement' that goes on in very detailed scenes where movement is involved. I will classify this as noise although I'm not sure if I'm correct in this. An example would be looking at a person wearing a sports coat with lots of criss-cross patterns. American Football is another example. When the camera is in zoom i.e. the players are close-up the picture is phenomenal. But when theres a lot of high-speed action filmed from a distance there is a lot of associated 'noise' which tends to blurr things a bit. Also, with writing/letters on the screen there tends to be noise around letters, especially noticalble with white letters.
Interesteing to note, that this does not occur with movies from such stations as HDNET, KUNGFU, WORLD, FILMF, MONSTER etc. With film sources (original film transferred directly to 1080i) the picture is without any noise.
One thing I do suspect, is that the KDS-R70XBR2 shows everything - worts and all, where the ability to reproduce even the smallest details can be liability. I am strongly considering a scaler from DVDO - perhaps the iScan VP50, as I understand its scaling capabilities are excellent. I'm guessing that the noise I'm seeing can be erradicated with a high-powered scaling engine, especially for difficult diagonals etc. Does anyone have feedback on this. Quite honestly the 'noise' drives me barmy and I want to fix it. How can I get rid of this??!
Thanks from a fellow tweaker nut

Follow Ups:
... comming from your dishnet box. If you change the output to 720p there is an improvement with blurring but the picture is not as sharp.
...with a DLP projection set. Lots of "noise" on fast motion, and video-based material had halos/distortion. Didn't happen on all material or every source, but was a pretty constant annoyance.Turned out he had cranked the Sharpness control up to maximum, thinking that it would improve picture detail. I had him reset it to minimum, and everything was fine.
I don't know if this helps you, but you might want to look at your picture settings.
The video you get in your home is compressed from cable, satelite
blueray and HD-DVD. It is really good compression but it is by nature
compressed alot of HD quality is due to the quality of the compression
and bandwidth given to the signal. The issues that you speak of detailed
patterns on a shirt and fast motion are where compression start to
fall apart.You have a very detailed monitor (yay!)
You can now see how bad the source material is (BOO!).
Setup is very critical to eliminate motion artifacts. A proper professional calibration is best. However if you want to try yourself goto avsforum.com and look up the settings that other people have. There is variation between the calibrations of individual sets, choose a happy medium. I was not able to elimiate all artifacts but I have to look for them now. Happy tweaking.
It sounds like several issues. One is "mosquito noise", another is motion distortions. Crappy broadcasts can have all kinds of noise in them. They may never look great, but proper settings will help aleviate them at least somewhat.
Has the TV been profesionally calibrated? If not, what are the settings on your TV? DRC and a few other settings are crucial.
HTH,

Hi Jack and Panhead,Thanks for the responses.
Jack, I have left the DRC set at the factory default Mode 1 (reality 1 / clarity 40). Strangley enough sometimes I prefer the picture without the DRC active.
I did change out the Monster Cable HDMI cable I have been using just to check if it can be improved upon. This is Monster's top-of-the-line HDMI and I think I paid about 165.00 for it. I replaced it with one of the cheapies I bought at my local electronics store in Torrance, CA. I have two of these; one is 13ft and the other 6ft. The cheaper cable significantly improved the picture over the Monster cable. Whats even stranger is that the 13ft cable was better than the 6ft version - go figure! I am inclined to think that the Monster cable is faulty, becase it definitely should be better.
I think that source material has a lot to do with the 'noise' I'm seeing, because some material looks fantastic ie with little or no noise at all, whereas some is not too good. Any suggestions regarding specific calibration settings or DRCF settings would be appreciated. Thanks again...
Here's what I've got my TV set at. Yours will differ due to lighting and personal preference, but perhaps you can get a few tidbits.
Note, there is a difference between my settings for cable, and my HD DVD player.Picture Mode: Pro
Iris: 1
Picture: 58 (HD) 55 (cable)
Brightness: 33 (HD) 32(Cable)
Color 31 (HD) 30 (cable)
Hue:0
Sharpness: 15
Color Temp: Neutral
Noise Reduction: Off for HD, Low for TV (or off)
Direct Mode: Off
DRC: Cinemotion
DRC: Custom 3 (1, 1)
BN Soother: off
Advanced Iris: Low
Color Corrector: off
DTE: Low
Clear White: Off
Detail Enhancer: off
Black Corrector: Low
Gamma Corrector: Low
R-Gain: -10
G-Gain: -8
B-Gain: 0(HD) -5 (cable)
R-Bias: 0
G-Bias: -6 (HD) -5 (cable)
B-Bias: -7 (HD) -6 (cable)HTH,
Jack

DRC tends to add edge enhancement, I set it for 1,1.
When I get home, I'll look up my settings, they can make a big difference with seeing noise/crap from bad sources.
