Poor sd quality with vix 4.2

[kryton]

So since updating my ET8000 to vix 4.2, SD channel quality is very poor, visible lines on faces, rough jagged lines on cartoons etc.
I know people are aware of this and Abu made a script to run that kind of sorts the problem, but this script needs to be run each time the receiver comes out of standby. Which gets a bit much after a while.
Ive now gone back to vix 3.2 to fix the problem.
Im guessing its a driver issue?
Ive even read it could be skin related, but im getting the same issue with every skin ive tried, including the default vix-night HD skin

Does anybody know if this problem will be fixed in future image releases?.
I would like to beable to update my receiver so i can take advantage of the latest features.
