@Shahriar, Thanks for report.
Does Amarok or Dragon player do use GStreamer Plugins? If so, then unstalling VLC wouldn't help it out. But interestingly I found that, the Gstreamer Plugins do install the same codecs as VLC or MPlayer does. But again, if Amarok or Dragon player use GStreamer and couldn't find it, it cannot reach the main codec libs and cannot play the media file. Same thing happenes with Totem in Ubuntu. As I am not a KDE user, its hard ti find a solution for Kubuntu. I am sorry. Why not you do some reseach and find a way? -- Ubuntu Bangladesh | http://ubuntu.linux.org.bd ubuntu-bd@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bd
