Yes of course it change the IF frequency and signal strength
Consider the frequency 11642  on Horbird.
For lo switch 11700, this gives a IF frequency on cable between lnb and dvb
card of : 11642-9750 = 1892 Mhz which is a high frequency
For lo switch 11600, this gives a IF frequency on cable between lnb and dvb
card of : 11642-10600 = 1042 Mhz which is a more lower frequency

I think this libdvb5 is to rework completly.
Most of other DVB software havet this feature, including VLC
