For all you HT1000 owners: What settings have you changed from the default settings for your cinema setup? I realised the other day that all I've done is taken the default settings, changed it to cinema mode for widesceen and changed the picture to 'movie' and thats it! When I see white text on a black background I see the rainbow effect clearly. Maybe I have the contrast/brighness set too high? Any thoughts or suggestions greatly appreciated!
