I don't have QAM64 available so I cannot compare but tuning works quite 
well. Sometimes changing mux takes time (about 5 seconds) but usully 
it's about 2 seconds. The software is quite unstable so I'm not sure 
what is due to it and hardware.

Ok, I try that when I come home after this weekend.

So that's the way how the driver is made, maybe I can found some new 
information about register values when signal is QAM128.

Would it be useful that you could access my computer by ssh? If yes, we 
need to consider it if I cannot i2c sniff anything useful.
