I installed slitaz-cooking on a grub partition of my AMD E350 desktop, and everything runs reasonably well. I got slitaz mplayer installed and went to slackware.com to get the mplayer-plugin in the /extras directory, which I decompressed and tarred so that firefox registers the slackware mplayer plugin in the slitaz firefox browser plugins section. I tested it on france2.fr (Je parle francais.), but only got audio, no video. Let me tell you that xine and xine-plugin are good, but mplayer has charms unknown to xine when its plugin works.
(Oh yes, I disabled the xine plugin while using the mplayer plugin. And, xine plugin does not register until you manually copy the contents of /usr/share/xine into /usr/lib/mozilla/plugins.)
P. S. to get going in the latest cooking, you have to cancel the locale dialog that shows initially, then get xterm as a favorite application and start lxpanel. If you run 'sh .xinitrc', you get a missing directory error message.
