I've had that, usually occurs when I'm pressing the RS to put somebody on a run, so could be to do with that? Might change if you change everything to manual (data part has changed where you can change many things from auto if you haven't already).
Anyway, Huddlestone is my favorite player on the demo, he plays exactly how he does in real life. Some moments, very poor video quality, took it on my blacberry and it got even worst when I uploaded it for some reason.

First is a thunder bolt off of the post. Second is a screaming into the bottom corner and the third is just a Huddlestone long pass to Lennon. Pass might not look great through the video, but in the moment it was just awesome and demonstrated how good the passing is in this game, really crucial to take risks and try to play these type of balls, because it looks so great when you do it. Love his shooting too, very realistic and the way he usually shoots in real life for Spurs, some low driven shots, also shows shooting isn't just 'floaty', you just need to learn the system of shooting.
Hudd is superb on the game.. has a rocket of a shot just like in real life.
