Hi, just last month got myself the W2000 as well, its a cracking tv! I found the THX otimizer really good for setting the contrast, brightness etc. Its found on DVD's such as Finding Nemo, Monsters inc or Star Wars Revenge of the Sith.
The one thing I would recommend though is taking advantage of the HDMI connection on the TV, the difference in sound and vision is staggering when comparing and flicking between Scart and HDMI on my DVD player.
