I just realised there's a problem with versions of code. I'm using the code from http://www.linuxtv.org/hg/~anttip/af9015 However I suppose you want me to use the code from the main repository. Needless to say it doesn't work with 0x60 or 0x61 as the address for the tuner. Also if I could somehow get this working with the right code, I don't know how to set up the values in the tda182171_config struct. Jarryd.
