Please refer to my post dated 3rd July on the previous page (also kindly quoted in full by ChainsawAsh for your convenience on 19th August) for details of how Adywan’s ESB 1997 may be obtained. It’s a very nice preservation and worth acquiring. Alternatively, if you have a Spleen account, you’ll find the MKV (14 GB) version there. Invites to the Spleen are sadly closed, so it isn’t currently possible to join if you are not already a member.
I’m afraid I don’t know the answer to your second question. Adywan is currently working on SW Revisited (HD) and RotJ Revisited, so I suspect he already has his hands full.
