yes, I know that but haven't find the bug :( Tuner number 1 goes bad 
(sensitivity is not good) after tuner number 2 is enabled. If I disable 
tuner 2 then tuner 1 is OK. And if both tuners are enabled tuner 2 is OK.
For developer point of view it looks just like some streaming settings 
are wrong...

Hmm. looks like tuner 1 is poorer also under Windows?

Those are just values, you cannot compare Windows and Linux signals 
because driver reports what it reports and also software then shows what 
it wants to show... Linux driver reports signal between 0-0xffff.

No, I tested almost all MXL5005S tuner driver settings and any of those 
didn't help.
