I don't use Windows Media Center to watch TV, so I probably can't help here. It seems, though, that you must have told it to record (whether directly or as a consequence of another setting); I don't think it would just do that automatically. Can you find anywhere in the TV section where you can set anything about what shows you want to watch and/or record? If you told it that you always want to watch ESPN2, it might be recording it so that you can go back and watch anything you want from it later.
