European and UK users of the Xbox One are experiencing judder issues when using their new consoles to play video from their existing set top boxes.
One user describes problems occurring when trying to watch SkySports using the Xbox One.
The score ticker was juddery during Soccer Saturday, and Spanish football was dropping frames when the camera was panning.
The root of the problem seems to be a difference in the US and UK/Europe broadcasting systems. The US is set up to 60Hz, while UK and Europe broadcast TV at 50hZ .
Presumably this will be fixed with a patch in the coming weeks.
