Added 2021-07-29 16:42:40 +0000 UTCI'd like to share an update about the HD-VMD video.
Here’s the link to this video message just for Patrons https://youtu.be/oCiYnU7mWIA
Finally here’s the link to the newly updated version of the HD-VMD video https://youtu.be/07Z4iL8hy1A
UPDATE: The unviewable demo disc. Lots of people have tried various ways to watch this. on a personal level this is not something I’m interested in…but since I’m still getting requests for a copy of these files here’s the link I’ve been providing every time someone has asked https://u.pcloud.link/publink/show?code=kZz1mxXZ1s2aOudJCnfvio2t2ulb1y7XevEX

HD_V004.VMD has some nice repeating patterns that suggest that the first 256 bytes after each GOP header are encrypted. Repeated encrypted groups strongly point to a 16 byte block cipher, most likely AES or3-DES. Even though only a small portion of the video is encrypted, it's more than enough to mess everything up as all I frames are lost.
