Hello, first at all, excuse me if my english is not good, cause it's not my first language

an then, there is my question, whenI watch a movie on my bdp5200/12 sometime I have to stop it, and if I want to continue later the movie, I have to search manually for where I was when I stopped, I see people with other BR players, they can do it all the time, but for me, the bluray starts again à the begining

do you know what sould I do ?

Thank you
