Hi, I believe this is related to gstreamer0.10-ffmpeg, see this issue upstream at: http://bugzilla.gnome.org/show_bug.cgi?id=342962
I'm experiencing this with more than matroska files, almost all media on my system is sluggish with totem-gstreamer (verified using xv), but fast with totem-xine, vlc and mplayer (also using xv). -- ASF/WMV file stutters while playing https://launchpad.net/bugs/63420 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
