Looking at the README for the cx25840 driver, it notes that "I need to send the following 4 bytes to I2C address 0x43 0x00,0x16,0x70,0x4a" in order to get the tuner to work. With my NTSC PVR-500MCE I get the following in my dmesg output:
cx25840: *** I2C Write to no cx25840 device 0x43. I'm assuming that the MCE (or maybe it's just the PVR-500) listen for this "magic" at a different address. Does anyone know how that "magic" was derived and how I can get the corresponding info for my card? Or, would it be potentially harmful to my card to go through all the possible addresses to send that data to? * Jeff Williams <[EMAIL PROTECTED]> [2005-01-22 22:53:15]: > Ok, I haven't seen anyone else comment on this, so I plunged into it.
