Well, I haven't had much problem. As I'm only doing DVB-ip reception (no 
TV) I think it's been ok for now. Although, I'm worried to see signal 
strenght problems.

Is there any accurate way of seeing what's the signal strenght? I'm 
asking this because we're installing these cards on multiple 
set-top-boxes around the country. And having the signal strenght value 
would be a very good point for us as we could easely report the value 
and check if all is good with the antenna's installation.

If the signal varies between tuners, maybe is there some kind of table 
referencing, per card, what is a good signal?

Thanks for the info!
