    No idea if I get NICAM audio, I just have regular cable in the US
    (Adelphia cable in Ohio). But, just in case, do you know what the
    register is? Daniel O'Conner posted links for the bt878 chip specs,
    but I don't think that's exactly what I need, since I believe the
    FreeBSD bktr driver supports the 878 as a chip. I need the specs for
    the TV Wonder, which I probably can't get without signing an NDA. I'm
    looking through the Linux bttv driver, but that's little help. The
    settings I tried using don't help at all, so it might be in the msp34xx
    driver. I'll keep hacking on it, and see if I can get it working.
