Gary,
First ,there is no benefit in using the I-Scan with the 11ht.
The 11ht has an excellent scaler and de-interlacer with its applications of DRC being- i.m.h.o. -better than the I-SCAN.
My advice ;-sell the I-SCAN.
Next,buy the Avia test disc-a must.
Once you have the Avia test disc-you can begin calibrations-with the aim being to get realistic skin tones of the LOW setting(6500k) and the punch of the custom1.
Go into the service menu by ENTER,ENTER,UP,DOWN arrows,ENTER.
Go into r.g.b.settings(gain) and note the numerical values within custom 1. write these down.
DO NOT ADJUST BIAS.
Then create your own custom-I used 4 and changed the values to the custom 1 setting then switched between custom 1 and LOW -Continually comparing to the custom 4 I was changing.(also note the original custom 4 values should you ever want to change them back.).
Once you have done this,use the Avia dvd to adjust contrast/colour etc..
This is very simple.
It is no good me giving you my settings as they are unique to my projector and vary down to the source and how you have calibrated your picture.
One tip I can give you-and you will see when you calibrate using AVIA.Is that sharpness SHOULD NOT BE ABOVE 7 for dvd watching.
Above 7 and you are blooming.
On SKYDIGITAL though i have set to 30 if the picture is soft and 21 if not so soft.
Once you have done this,the next step is a fullblown SMART calibration which involves measuring grey levels at different points of IRE and trying to achieve as close to 6500k through the grey scale.
Having said this,I have seen pictures from some SMART calibrated Sonys that look AWFUL...
Total greyscale accuracy equating to close to 6500k can produce a rather dull picture not to everyones taste.
Even after SMART calibrations with their s/ware-you would still need to tweak by eye.
Sometimes after SMART you still need a colour correcting filter to tame red push etc...
It can -as you say- get quite complicated.
But remember,the 11ht is capable of some of the best images in the world if correctly set-up.
At the moment you are seeing it at 20% of what it is capable of.
