So I used DVD decryptor on two of my DVD's Saw 4 and Charlie Bartlett. Then I used freez to convert them into mp4. But 1 of the four segments of charlie bartlett has the directors commentary on it which ruins it of course. And 1 of the 4 sections of saw 4 won't decrypt for some reason. I wish it would either work all the way or not at all instead of giving me 3 of the 4 parts. Any idea of what I can do?
