    You may be referring to something I posted, I had read that you could 
    not load the ntsc and the dvb drivers at the same time. I read this
    in the Gentoo HowTo setup MythTV, but I think that information pre-
    dated the integration of the hd-3000 drivers into the kernel, and may
    no longer be valid. 

    But I have also seen several references to removing the analog driver
    and (re) installing the dvb one.

    My system loads both, and I have not seen any problems that I can say
    with certainty are related to that, but I would like a definitive 
    answer, is it OK to load both driver modules ??

    I am having some problems with QAM, and if the analog cx88 module is
    contributing to them I'd like to know it, otherwise I don't want to
    waste time disabling something harmless.

  Ok, well then, I will be testing this shortly and get back with my results.
