If the files are Windows Media Video 9 (FourCC code WMV3) format, it looks like you will need gstreamer 1.2.3 or later - see the "GStreamer Plugins Base:" section of http://lists.freedesktop.org/archives /gstreamer-devel/2014-February/046109.html
Ubuntu 14.04 "Trusty Tahr" currently has gst-plugins-base1.0 version 1.2.3-1. Can you test and see if it works? ** Changed in: pitivi (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1257286 Title: can't import To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pitivi/+bug/1257286/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
