UE40D6530 -- Tweaks and calibration advice, please?

Hi there,

I've just bought this TV, and would be very grateful if anybody could suggest some tweaks and calibration settings so that I can get the best out of the picture. I bought it because I read very positive reviews about the SD picture, and although it's pretty good out of the box it really isn't the quality of picture I expected to see. I think that's prolly because I need to calibrate it.

This is my first 'modern' television, and I'm completely at sea with the new technology and terminology. If there's a place where I can start to learn about it then I'd be grateful for a link. I've been reading around a couple of forums for a couple of days, but everybody knows so much more than me that it's as though they're speaking a foreign language

I also got the (free) Samsung BD-C5900 Blu-ray Disc/DVD player, and bought a Humax HDR-Fox T2 PVR. I have them both attached (via HDMI) and working, but I'm not sure whether I also need to adjust their settings to work best with the television. Newbie question, but... should I expect to use the Humax as a source for viewing?

Many thanks for any help anyone can give a newbie
