Your signal strength is not enough. I think Linux mxl5005s tuner driver 
does not have as good performance as Windows. You can try to change some 
tuner parameters (in ec168.c file) to see if you will found some more 
sensitivity.

I think this register contains demodulator lock bits. When it is 0cf6 
demod is fully locked. No lock here...

I should add one ms sleep to avoid this.
