So far, I've only found the one bad disc from the MAN FROM UNCLE set from Warner/Time Life. I will begin scanning season 3 next week. This is the set that was released in the attache case.
Season 2, disc 6 of Warner's MAN FROM UNCLE DVD set of the TV series (the 2008 release in the attache case) is now freezing up. I don't see any disc bronzing, but the disc won't play properly.
