Hi, I have had my 436 for about a month now and am very pleased with it on the whole. Anyway, only yesterday, a guy at my local dealer told me that I should turn of "DNS" when setting up the contrast, brightness, colour, sharpness & tint using my Ovation Software DVD. However, I was wondering if I should turn of "Pure Cinema", "CTI" and any other processing features also? Most of the time I'm watching DVD's via HDMI and was wondering if I should just turn of all processing as the signal is digital anyway? The only problem is I'm sure SKY would benefit from DNR and possibly Pure Cinema (not 100% on what this actually does)?
