For some reason apple removed support for the quicktime SDK so this version switched to the gstreamer plugin just as the linux and windows version has done.
You will need to install the gstreamer package to play movies. Until there is a 64bit build, you will need the 32bit binaries from here:
https://gstreamer.freedesktop.org/data/pkg/osx/1.4.5/ - gstreamer-1.0-1.4.5-universal.pkg
(edit, renamed the files incorrectly, is fixed now)
