I don't own the datasheet of the TDA10023. I think you must read the config= uration of the = TDA10023 from windows. This can be done with this program = (http://linuxtv.org/downloads/saa7146dump-0.2.zip). If it is necessary to m= onitor the = initialization of the tuner chip, you must use an i2c-monitor. I developed = a cheap monitor = (http://www.vdr-portal.de/board/thread.php?postid=3D639818#post639818). The= costs of the = parts are less then 10=A4. To build such a monitor, you should know what a = soldering-iron is. -Hartmut Birr _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
