So, I answered question one and two.
The versions available on ulozto are only 14GB for the entire trilogy, DTS is non-existant, as well as other audio tracks and they are compressed to death.
As I see on the pastebin NFO for the Trilogy the sizes are as follows.
SW 2.7: 19.9 GB
ESB 2.0: 19.7 GB
ROTJ 2.5: 19.2 GB
Result: I’m back where I started. All official pastebin links are dead. If ANYONE has any suggestions on how to obtain these in their full video and audio format I would be eternally grateful.
PS I own the official Blu-ray discs as well as the Laser Disc Trilogy with the Book, DVD Trilogy and the VHS Trilogy.
May The Force Be With You,
