Trying to find 

BBC ONE;BBC:506000:B8:T:27500:600:601=eng,602=eng:0:0:4164:9018:4100:0

with w_scan gives me this log output when tuning with mt2060 debug=1;

Nov  7 14:40:58 htpc kernel: MT2060: PLL freq=506000kHz
f_lo1=1726000kHz  f_lo2=1183850kHz
Nov  7 14:40:58 htpc kernel: MT2060: PLL div1=107  num1=56  div2=73
num2=8115
Nov  7 14:40:58 htpc kernel: MT2060: PLL [1..5]: 5e 6b  3 fb 93
Nov  7 14:40:59 htpc kernel: MT2060: IF1: 1220MHz

This seems to look ok? Is there any way of finding the PLL values the
tuner uses when running under windows?

Trying to tune to original frequency with offset applied gives this log
output;

Nov  7 14:45:34 htpc kernel: MT2060: IF1: 1220MHz
Nov  7 14:45:34 htpc kernel: MT2060: PLL freq=505833kHz
f_lo1=1725750kHz  f_lo2=1183750kHz
Nov  7 14:45:34 htpc kernel: MT2060: PLL div1=107  num1=55  div2=73
num2=8064
Nov  7 14:45:34 htpc kernel: MT2060: PLL [1..5]: 5d 6b 30 f8 93

tzap seems to be unable to tune to 506000khz, even with a modified
channel conf file it insists on tuning to 505833khz. Maybe it tries to
interpret the stream and retunes to that frequency?
