As for 2 different copies of the disc erroring out in the same place, were both of these discs attempted on the same optical drive? Have you tried a different drive? I've discovered some drives, particularly LG's, don't like to read 100% of all discs that other drives, like Pioneers, will. This is one reason why I keep a few USB drives on hand. To easily connect and do a decrypt if my workhorse LG doesn't read a particular one. Had that happen recently. On a DVD-R with no encryption on it at all. AnyDVD wouldn't make an ISO of it in the LG, but would in my USB Pioneer.
