The 1997 laserdisc credits were video-generated. The credits on the 1997 digital broadcasts and the 2004/2011 DVD/Blu-ray releases are the ones that appeared on the SE theatrical prints. (The end credits were not changed for any of the films in 2004; instead, the new credits appeared as a supplement on the fourth bonus disc.)

I'm not sure why they altered the credits for ANH; was it to add those names, or just to make the credits easier to read?

I do know that at least the opening "fade in/fade out" sections of the end credits of ESB (and possibly ROTJ) were also video-generated on VHS/LD, because they forgot to add James Earl Jones to the SE credits the first time. (Consequently, Jones' credit was absent again in 2004.) The scrolling credits for Empire and Jedi were still the theatrical versions, at least as I remember it; I recall the ESB credit roll being almost illegible on the widescreen VHS.
