So just in case you have to do this, here is a utility to adjusts the MBR so that GRUB doesn’t load any more. After you run this all you have to do is delete the partition.
Then all you need to do is run the command:
MbrFix /drive 0 fixmbr /yes
Download the Essential Codecs package from the mplayers homepage http://www.mplayerhq.hu/design7/dload.html
Unzip and move to the directory: /usr/local/lib/codecs (create if it does not exist, need to use SUDO command)
Then run these two lines of code:
cd ~/.gnome2/totem-addons
for file in /usr/local/lib/codecs/* ; do ln -sf $file && chmod +r $file ; done
