Launch synaptic, then search and mark for installation, ubuntu-
restricted, NOT xubuntu, kubuntu this is a great newbie way to take
the guess work out of all the extra stuff needed for media playback.
If you are running compiz-fusion or any other accelerated desktop,
turn the effects off, unless you go through each of your video media
players and make adjustments to the video output, such as changing
open-gl to x11 xvid ect. I distro. hop often and the one thing I
remember is that an updated Gos handles playback of most, including
wmv in the browser better then most distros. with less tweaking. If
you don't have a launchpad acct. get one, as the Ubuntu forums have
many answers as well as here as Gos uses Gnome 2.22.2 as of the 3.0
release which is the same as Ubuntu 8.04 LTS Hardy with Google gadgets
installed and configured and the Wbar installed and configured and
allot of fine tunning as well.
The installed media players should pick up the codecs in gstreamer-bad/
ugly, ect. I don't remember if w 32 or css is installed with this
script as this could be a legal issue depending on where you live.
