If you add an LSB to 7h (arbitrary value),it become 1Dh
Looks easy enough for me as astarting point,
But the values to try for starters will be 2^56.I know,is bad.
If you see some macroblocking is maybe because part of the video packet is not encrypted and decoder is able to build part of the image with that information.
But to know which part of the video packet is not encrypted is not easy either.
Maybe they don;t encrypt parts of the packets on purpose,is all a guess game at this point.
