I have one of these. Are you sure there are TDA9874H chips? I have one on the daughter card. Where is the other one? Anyway, you need something to initialise the TAD9874. I hacked on the TDA9875 driver, removing most of it. All I have is an init function which sets the chip up into NICAM B/G for me. You probably need to alter this for your needs. Get the data sheet from the Philips site here: http://www-us6.semiconductors.com/acrobat/datasheets/TDA9874H_2.pdf Most of the setup should be right, just look at the ESP register setting and page 42 of the datasheet. I'll put the code down the bottom. I load the following modules: modprobe i2c-core modprobe tuner modprobe tda9874 modprobe bttv in the bttv-cards.c file I have: name: "FlyVideo 2000S", video_inputs: 3, audio_inputs: 1, tuner: 0, svhs: 2, gpiomask: 0x18e0, muxsel: {2, 3, 0, 1}, audiomux: { 0x1000, 0x080, 0, 0, 0, 0 }, pll: PLL_28, tuner_type: TUNER_PHILIPS_PAL, I haven't actually had time to really test this (had the parameters in the modules.conf file and transferred them to here). This still needs a lot more work. tda9874.c needs to have parameters for video standard etc. Let me know whether this works for you.
