Allows proper tuning around high/low band boundaries when using non "standard" LNBs. Not all LNBs (Low noise block down converters) are made equal. This is particularly true for universal LNBFs, where, even though there are seemingly standard values for the local oscillator frequencies, these can vary from manufacturer to manufacturer and LNB model. Change also proxies the new LNB properties in dvbbasebin. https://bugzilla.gnome.org/show_bug.cgi?id=732818
