One - If you are hooking a Wii up to a TV that uses the 'Y' (green) channel of the component video input for also decoding the composite video input, expect it to look dark if you use the Wii's composite video cable. Obviously if you have the component video cable for the Wii, you should use that when possible. I happened to notice it over the weekend when my son got to play Sengoku Basara on the TV at my Dad's house. I presume that it's because there's less signal to go around, so the TV assumes that the picture isn't as bright (even though I'm sure the TV's electronics are fully capable of compensating for it.) I had the chance to go get the other cable, and turned progressive scan back on, and the picture was pretty much back to normal brightness. If you were confused by the use of the words 'component' and 'composite' in this context, refer back to my post about HDTV.
Two - If you didn't have the Netflix channel loaded on your Wii before you put in The Legend of Zelda:Skyward Sword, the Wii will do a 'System Update' that adds it for you. Funny, I just checked for a new system update the other day when I reset my router.
