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.
