Thanks to everyone replied to my thread.
Found the problem was the Openatv image, when I change the image to openpil, in my living room was like setting in a cinema sterio sound and so high.
So the ET8500 as hardware machine I can't fault it in anyway it's very fast and well bult.
One think I can't get the new 1.6 sky skin working on openpil.
Any help would be really appreciated.
Thanks to all.
