Pack an is a good idea. But SUSE has been clever.
SUSE 12.2 is e,g. Leap 42.2
SUSE 12.3 is Leap 42.3
so both systems are very alike.
You can use a installer from opensuse "media files" as well and install the missing condecs. Then install VLC player NOT from SUSE or Open Suse but directly or from packman. You cange the default application in YAST-Settings-Details to VLC.
For Firefox you need to install HTML5- Flash add and for Facebook Facebook flash codec.
Then it works.
