Приветствую, Mike
the rotor plugin ( or at least version 1.4mh) can control one rotor per card.
For c-band you need a vbox to translate the diseqc commands and to provide the 36 volts to drive the actuator. Thats how I do it. costs about $40
why need vbox for C-band ? I can watch C-band with vdr + rotor + diseqc + 3 Lnb (two LNB are for Ku band, third LNB is for C-band) without any tricks
