I have several films that have an mkv file extension. When I browse unp, these films do not show - it's as if they don't exist. By the way, they don't show up if I try to access them on my computer using Media Center. Other players are ok with them.
Another problem, some of my avi films will not play. I assume that it has to do with codecs - is there a way to add codecs to the Box Office"?
