Ubuntu 7的源裡缺少w32codecs，想看rmvb麻煩，所以找到下面的源
Installing libdvdcss2 and w32 video codecs in Ubuntu Feisty Fawn
Support for WMV, RealMedia and other formats has been bundled into the w32codecs package. This package is not available from the Ubuntu repositories due to licensing and legal restrictions.
Edit /etc/apt/sources.list file and enter the following repositories save and exit the file
sudo gedit /etc/apt/sources.list
For Ubuntu Feisty Fawn Users
deb http://medibuntu.sos-sts.com/repo/ feisty free non-free
deb-src http://medibuntu.sos-sts.com/repo/ feisty free non-free
Now you need to copy the key using the following command
wget -q http://packages.medibuntu.org/medibuntu-key.gpg -O- | sudo apt-key add -
Update the source list using the following command
sudo apt-get update
Install Codecs using the following command
sudo apt-get install w32codecs libdvdcss2
Using above download locations you can install most of the mutimedia codecs for ubuntu.
