The patch _is_ universal :). It works with version available on the website (mplayer-1.0pre3), and with cvs version. The first one will give you some hunks, but ignore them.
Download the patch: mpl2.diff
Installing the patch:
1. Copy it to the directory with mplayer sources. 2. While in that directory, execute: patch -p1 < mpl2.diff 3. Compile and watch.
The patch was made by Cezary Jackiewicz and the motto of this page are his words:
As for working - i've watched several seasons of Star Trek using mplayer and this patch - it works perfectly :)
