I'm shure the cx23883 has to programmed in a different way for digital tv. No capturing of an analogue video signal is needed but the transport of digital data. > So is the I2C bus used to control the tuner and > decoder? I think so although I've seen one tuner which is controlled via a 3-wire bus. > > Sniffing on the i2c-bus of the mt352 may help to > > answer some questions. > > How would I do that? Find out the positions of the I2C-Bus lines clock and data and connect them to the parallel port: http://warmcat.com/milksop/cheapi2c.html. Don't forget the GND wire. Start the WIndows-Software and look what's going on... Wolfram
