OK back again - I did a fresh install in the hopes of narrowing down what is causing the problem.
I also documented exactly what packages were installed after the installation, tested 3 different mpegs each time something was installed, both before and after a boo - see attachedt. The final result seems to be that installation of gstreamer from the bad set, or one of the dependencies is at fault. Snag is that in order to play these files totem requires these codecs. ** Attachment added: "steps to recreate freeze with mpeg.txt" http://launchpadlibrarian.net/19627548/steps%20to%20recreate%20freeze%20with%20mpeg.txt -- right click to get property of mpeg freezes nautilus https://bugs.launchpad.net/bugs/296969 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
