Re: Fwd: Re: Re: Problems with Linux drivers (Debian Jessie kernel 3.16.0-4)

According to logs, everything seems to be fine. You could not compare 
statistics numbers between two drivers. SNR 0096 is 150DEC, which means 
15dB, IIRC it was max chip could return for DVB-S.

No idea about sync etc. problems, are you sure about those? I am pretty 
sure it works rather well as I haven't got bug reports from PCTV 461e 
users which has that same demod + tuner.

regards
Antti
