* Copyright (C) 2003 Roy Bulter <rbulter@hetnet.nl>

*
* Copyright (C) 2000-2001 Gillem <htoa@gmx.net>
* Copyright (C) 2002 Andreas Oberritter <obi@saftware.de>
*
* Based on Stadis 4:2:2 MPEG-2 Decoder Driver by Nathan Laredo
*
* Copyright (C) 1999 Nathan Laredo <laredo@gnu.org>
*
* This driver is designed for the Hauppauge 250/350 Linux driver

*
* Note: the saa7126 is identical to the saa7127, and the saa7128 is
* identical to the saa7129, except that the saa7126 and saa7128 have
* macrovision anti-taping support. This driver will almost certainly
* work fine for those chips, except of course for the missing anti-taping
* support.
