Ah, didn't know that, good to know. I'd seen someone else's post about having
to change the QAM type in siscan.cpp to get 64, and have been having some
problems getting my own Air2PC card to pick up anything off own cable
service. Haven't figured out what QAM type they're using yet, so this little
patch made it easier to flip back and forth between the two.
