I have a Sky puck too, mine has been playing up, but only over the past couple of weeks, I've had mine for over a year. The moving on to the next programme seems to happen to me only when I watch something that has already started, and choose to watch it from the start and then I fast forward through the ads, it happened last night. Also recently, around midnight, it seems to get stuck and replays the last few seconds of a programme over and over until I stop it! I don't know anyone else with a puck so it's good to hear your experiences.
