Ok I have media files that open in media player. In order to use them in hoster I have to click video and open them up, but I cannot do a search for them cause they are not kma. How can I make them Kma or am I SOL? If so no big deal I will just have to make a list of vcds that I have on media player. These were originally vcds but are now media files.
