For those who are interested I've done the subs for dark_jedi's ANH '97SE forthcoming disc and decided to share some observations I did when working on them, some may find it interesting.
The timings and the appearence of the '97 LD/VHS subs are not identical to the theatrical subs where I do have a reference to look at, the same goes for the '04 DVD subs. Here is all the lines that differ from each other.
Greedo:
'97 LD - "...every bounty hunter in the galaxy will be looking for you."
'04 DVD - "every bounty hunter in the galaxy will be looking for you."
'97 LD - "He has no time for smugglers who drop their shipments..."
'04 DVD - "He has no time for smugglers..."
'97 LD - "...at the first sign of an Imperial cruiser."
'04 DVD - "who drop their shipments at the first sign of an Imperial cruiser."
Jabba:
'97 LD - "Solo, come out of there, Solo!"
'04 DVD - "Solo! Come out of there, Solo!"
'97 LD - "So, for an extra twenty percent..."
'04 DVD - "So, for an extra 20%--"
'97 LD - "Okay, fifteen percent."
'04 DVD - "Okay, 15%."
'97 LD/'04 DVD - "But if you fail me again..."
Theatrical - "But, if you fail me again..."
'97 LD - "You won’t be able to go near a civilized system."
Theatrical/'04 DVD - "you won’t be able to go near a civilized system."
Also the DVD subs have the word "Imperial" with a lowercase i. The lines that are split up doesn't have an ellipsis before the continuing line in the SE as the Original had, you can see this in the screen-caps on the first page. Now, I'll end my useless ranting... ;)
