[KLF] PDO Discs

Hi all, Can somebody with experience with sending discs with "laser rot" back to PDO give me a quick explanation of what that are and aren't willing to do? My copies of "Shag Times", "Chill Out", "Give Peace a Dance", and "Monty Python - The Final Rip-off" all have varying degrees of the problem. Thanks, Michael PS: Sorry if this arrives twice, but am I right in thinking that if you're not subscribed to the new list yet, then mail sent to the new address is not being forwarded?
