/* 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
