I have loaded three video wallpapers to the iphone using winterboard......its great, but they dont seem to work 100%......when i first check one off in winterboard and then it resets, it works flawlessly.....but then after the phone sleeps for a certain period of time, when i wake it the background isnt there and its just blank....the only way to get it back is to reload it in winterboard....am i missing a setting or are these video wallpapers just not 100%? thanks
