Sorry for the late reply people. I'll try and answer in order:
Bill:
Nightmare that you're still having problems and I think it is about time you considered the Aconda. As Stretcher has mentioned, you can almost eradicate the Moire using a solution that I will post below. I say almost because what it does is really compress the Moire pattern to a point where it becomes invisible from any more than 3 ft away. It is simply not there from a normal viewing distance of 8 to 9 ft away. My solution which I posted ages ago (in a now deleted thread) is as follows:
I have had the 9381ZW Aconda for some time now and started to notice those effects shortly after I purchased the set. On mine, it only happens on R1 pure NTSC signals via DVD. It used to also happen on analogue PAL in CINE and ZOOM modes but since upgrading to Sky Digital, this no longer occurs at all.
I was getting tired of the effect on NTSC material and it is indeed down to geometry distortion causing a slight Moire effect. You'll notice that changing aspect ratios changes the nature of the moire pattern. In Pan mode, the moire should be gone completely.
The nature of the moire pattern seems to be linked to two parameters in the service menu:
1. V Amplitude
2. S Correction
V Amplitude adjusts the vertical size on the image. S Correction adjusts the vertical size of the mid portion of the screen only. The default for this parameter on NTSC material was 11 on my Aconda. So I paused a NTSC DVD (Predator) on a scene that showed the moire quite significantly and adjusted the S Correction parameter. I brought the value down from 11 to 3 and the moire dissappeared before my very eyes!
Problem solved.
Only do this if you are not afraid to access the service menu yourself. Otherwise call an engineer out but he will most likely just do the same thing.
To enter the service menu:
**** WRITE ALL DEFAULT SETTINGS DOWN BEFORE MAKING ANY CHANGES ****
Press the Menu Button on the TV until the service option is highlighted, then quickely press "M" on the remote. Scroll through the geometry options with the up and down controls and change values with left/right. Store new values with OK. If you do not wish to store just pres "E" to exit the service menu.
Let me know how you all get on
