downloaded avi...audio but no video
 

well the best place to look for the drivers will be
www.divx-digest.com you will also find the divx5 and xvid
codecs and the ac3 audio codecs, all of which you will
need soon if you're downloading video from the net. can
i also recommend www.winmx.com to get winmx which is
probably the best peer to peer software out there.

hope that helped.
