Could be down to how each of the different drives in the different PC's "reads" the data? Maybe one drive does some kind of data reading that the other doesn't?
As long as the discs read to an image, I wouldn't be too worried about differing CRC's. If you're really worried, then watch the discs' contents in a DVD player. If they play fine, then I wouldn't worry. There are so many other things in life to worry about.
To be honest, I could consider myself a kind of paranoid regarding to this kind of matter. Yeah, the content of the ISO is fully playable but this crc difference makes me wonder if there is some kind of video data missing.
Related to this, there have been times that while I have not received any error when creating a ISO, I receive misscompare error messages when I verify that ISO image against the disc inside the drive. I cannot understand why either.
The disc has some skratches, could this missmatch be caused by this?
