/*
* vo_dxr3.c - DXR3/H+ video out
*
* Copyright (C) 2002 David Holm <dholm@iname.com>
*
*/
/* ChangeLog added 2002-01-10
* 2002-01-17:
* Testrelease of new sync engine (using previously undocumented feature of em8300).
*
* 2002-01-15:
* Preliminary subpic support with -vc mpegpes and dvd's
* Device interfaces tries the new naming scheme by default (even though most users probably still use the old one)
*
* 2002-01-10:
* I rehauled the entire codebase. I have now changed to
* Kernighan & Ritchie codingstyle, please mail me if you
* find any inconcistencies.
