 systems...

 /* ChangeLog added 2002-01-10
+ * 2002-02-09:
+ *  Thanks to the new control() method I have finally been able to enable the em8300 prebuffering.
+ *  This should speed up playback on all systems, the vout cpu usage should rocket since I will be hogging
+ *  the pci bus. Not to worry though, since frames are prebuffered it should be able to take a few blows
+ *  if you start doing other stuff simultaneously.
+ *
  * 2002-02-03:
  *  Removal of libmp1e, libavcodec has finally become faster (and it's code is helluva lot cleaner)
- *  We will call this one the "gentoo" release in favour of the gentoo linux distribution (www.gentoo.org), which
- *  aims at providing maximum performance
  *
  * 2002-02-02:
  *  Cleaned out some old code which might have slowed down writes
