I've been backing up my Disney Treasures Collection so I don't have to worry about scratching the original discs. I've got 44 discs. However one of the discs (Silly Symphonies Disc 2) about 40% into the decryption, I get ongoing Semaphore timeout errors and I can't rip the disc. This is READING people, not writing. The disc looks brand new. I'm running a BenQ DW1655 in a MadDog USB2 enclosure. No problems with the other discs! Firmware version says HOQ4 I believe. Help!
