Hello, I tried to copy different files to my samsung P6800, for .flv files I got message that this file might not be run on the device so I skip the file and also select the option saying something like "use this preference for all such files" now i have installed .flv player but when i try to copy it, it fails. Now how can i change that preference/settings which i checked. now i am not getting any message or option and i dont know where to go to uncheck it. please someone help me.. Thanks.
