Hi, I go a few issues while trying to play this: http://yozora-irc.net/~ubitux/vids/natsume-mkv-issues.mkv First, the sound is not good and there is a big a-v sync issue related to it. I also get a font-size issue with ass rendering (internal and external libass): you can see it well when displaying the episode title, there is an overflow. So I tried the lavf demuxer, which fix the audio issues. But I don't get the ass rendering for ass subtitles. Of course, I use latest svn revision (r31029). Regards, -- ubitux
