There are several reports in this thread about those DVDs in Volume 2 not working. A few weeks back I checked my boxset and had zero problems with any of those discs. WA does offer replacement discs, but with the "stay at home" order in California, disc replacements aren't happening right now. There is a contact person at Warner, Sherri Bogard. I don't have her email address, but I'm sure somebody else will provide it to you so please, be patient and continue to read this thread.
For the record, I just sent Sherri Bogard an email around 3 this afternoon regarding my GOLD RAIDERS (1951)/MEET THE BARON (1933) DVD, on which the former is completely non playable. I've already received a reply from Sherri indicating they would be more than happy to exchange discs, which she can begin the process of doing once their offices are reopened! That was a far quicker response than I figured could be reasonably expected given the circumstances, and I very much look forward to receiving the reissued MOD disc of the above titles, whenever the current events that are preventing any exchange subside!Thanks so much. I will email her and hope to hear back I will let you know.
