Can you try the latest code?

Also, you may be right about CheckOptions(). It should also probably
be located in Tune() not in TuneMultiplex() and SetChannelByString().
And it shouldn't be doing the LOF stuff.

BTW Would anyone use LOF frequency shifting and not use DisEqC?

Maybe I can just rip it out of CheckOptions() altogether?
