How does GVPVR get clear QAM listings for cable TV?

It seems Comcast likes to constantly re-arrange their clear QAM lineup to keep their hard paying customers guessing, (and it is a PITA! - glad the FCC slammed them on their messing with transfer speeds for certain protocols! What a go, FCC!)

Do you mean the tuning parameters? It detects a channel in the stream when doing a channel scan which you then match to the appropriate EPG channel. When the channels move, you have to rescan and remap.
