You'll have to excuse me presumption here (I'll normally read all
messages before adding to a thread), but you sound like a very good
source of info here. May I ask you if you can supply some references to
what you're posting here? I'd like to investigate this much further...

Also, I thought I read somewhere that firmware is used in most tuners.
Plus I found the linux drivers use firmware to make this work. Just a
thought.
