Help! DVB-T lost sound problem with AutoGK

Hi' i've managed to find a program called AutoGK,(Gardian Knot) that can convert my Freecom DVB-T USB Sick vedeo files but the original narration on the finish converted file has been replaced by what seems to be editors or directors talking.
I recorded walking with dinosaurs but the converted file has people discribing the scences i.e: "Dinosaur jumps on to rock" then pauses and "Dinosaurs turns to left".
It's like the editor talking, whats happened to the original sound track, can anyone help? thanx.
