MapQuest Satellite tiles are currently broken. In the OpenStreetMapQuestSatteliteProvider class, the current URL format is:
"http://oatile{0}.mqcdn.com/naip/{1}/{2}/{3}.png"
But according to this (http://wiki.openstreetmap.org/wiki/Mapquest#Tile_URLs), the URL Format should be:
"http://otile{0}.mqcdn.com/tiles/1.0.0/sat/{1}/{2}/{3}.jpg"
I have tested this modification in the latest changeset and it works.
