You Tube is almost unusable on the 2 XS. Goggle continues to update the app for the newest boxes, and makes it run terrible on the older, slower boxes. I haven't seen that particular problem with mine, but I must confess that my 2 XS is rarely even powered on any more. It's just too old and slow for everything. I can't use it to watch movies from my DLNA server because it can't handle an HD video bitstream. It maxes out around 14 Mbps, and all of my HD movies stream at least 20 Mbps (or much higher).
