How to using mplayer in Ubuntu

Today, i bought a pioneer DVD MULTI Recorder which cost me 320 RMB, sigh...
Afternoon, I installed mplayer for my Ubuntu.
The steps as follows:
1. using synaptic package manager search and install svn (subversion version control client). It may require some dependency packages.
2. search and install gtk 2.0 package.
3. search and install fakeroot.
4. get mplayer from svn as follows:
#svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer
now, trunk will rename to mplayer
5. get codec as follows:
http://www1.mplayerhp.hu/MPlayer/releases/codecs/all-20060501.tar.bz2
6. copy all the all-20060501 released files to /usr/local/lib/codecs
7. run ./configure in mplayer directory. it may want's u install gcc 3.0 or higher. u can install from synaptic package manager.
8. make and make install. (by defualt, Ubuntu will not install make program, also, u can install this by SPM).
9. type mplayer , enjoy music and movies. :)
