I had that issue for a while, but now it shows me the most viewed videos. Someone above said that you need to be connected through 3G for that info to load.
Even so, is anyone finding this widget useful at all? It just scrolls through the same 3 videos, and there's no way to actually access the app through the widget. You can only either view one of those 3 videos or enter the search dialog, both of which are usually useless. Is there a way to actually access the app through the widget?
