hehe yes.

Make gstreamer optional and if defined it is used exclusively for both 
audio and video extraction (all others are disabled). If no metadata 
found then do *not* try others (xdgmime sometimes incorrectly identifies 
large binary files as avi video files and they will obviously not have 
any metadata)

Can Xine perform audio extraction? If not make it optional or discard it 
 (I dont mind which)

If none of the above enabled, then default to totem and mplayer

I will probably have to make the debs use gstreamer if we want to get 
all audio stuff that we dont currently support (IE FLAC and mp4)
