You can also download the latest decoding package by yourself to the MPlayer Web site, where http://www.mplayerhq.hu/design7/dload.html select "Binary Codec Packages" under the heading "Linux x86 ... ", such as Linux x86 20061022, download after the/usr/lib/codecs/or/usr/lib/win32 can be extracted.

For example

sudo mkdir/usr/lib/codecs/
Cd/tmp
Wget-c http://www1.mplayerhq.hu/MPlayer/releases/codecs/essential-20071007.tar.bz2
Tar jxvf essential-20071007.tar.bz2
