What you need to do is scan your i2c bus. Get the sensors-detect script that comes with lm_sensors, and run it. It should tell you which devices are available on your system. It will probably not identify your video decode chip, because it's mainly aimed at sensor chips, but at least it'll tell you at which address the chips were found (you can also use i2cdetect to obtain the same information). -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
