I've checked all the disks I received from Vintage Theatre and only Disk 2 seems not to work. It just slips in my DVD player.Probably due to the paper sticker they put on them. They were very easy to talk with and said they would replace all bad disks. Picture quality is very good. As good as remember them at the theater when I was young.
I am very pleased to her that this dealer is treating you correctly. Please keep us informed as to what transpires, as your favorable comments can benefit them just as negative feedback can have the opposite effect!
