Neither really, it's evolved into more of an issue about an inability to display video files on the TV-out - it's just VLC Kumaki was using to begin with. On the other hand, if you are aware how to get smooth TV-Out working on VLC, it would probably be welcome..
I've had no luck with VLC or Gnome mplayer to display at all with the TV-Out.. However this weekend I was playing with the latest version of Smplayer2 and it works when I select "HW scaler / Overlay" in the TV-out configuration tool.
