Thanks John Lucas, I think I know what it is though now... Check yourself the time it recorded "other" for SMG, I would bet it is the 11th one down.
@tabsina. No it can't be because i have done that recently and it never counted it, wheras in the past i always went back to the menu.
@thanny. Well i have done that a few times, but i doubt it adds up to more than 5 hours because i usually turn it off.
