I just go the unit and have been playing with it. Previously, I used "PlayOn" as my media server. PlayOn supported .mkv files and also would show a movie picture on the video when browsing if you had an image with the same name of the video in the same folder. The LS-2.0TL does not seem to be able to do either of these options.
Is it possible to play .mkv files and does this media server support any kind of images that link to movies or media data?
