So maybe someone should provide a download of the needed 32bit
gstreamer libraries :) I think that if linden did this sort of like
Pheonix does with the SLVoice where the first launch it downloads any
extra libraries and puts them in the libs/bins folder. Is this a
practice linden might be interested in?
