Review
Almost completely reworded, consistency and spellchecking. Removed "Compiling MPlayer" section for lack of useful information. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@6878 b3059339-0415-0410-9bf9-f77b7e298cf2

<P>You can reduce the drive speed with hdparm or a program called setcd.

It works like this:</P>
|

|

<P> <CODE>hdparm -E [speed] [cdrom device]</CODE></P>

<P> <CODE>setcd -x [speed] [cdrom device]</CODE></P>

It's recommended that you tuneup your CDROM drive also with hdparm:</P>
|

<P>This sets prefetched file reading to 2MB, which helps with scratched CD-ROMs.

It is recommended that you also tune your CD-ROM drive with hdparm:</P>
