Um, isn't the 81 version just the 77 version with the Episode IV crawl and a slightly different sound mix?
Doesn't it have also different colouring? You know like the artificial darkening of the "R2 in the canyon" sequence, or the different colours of the binary sunset sequence ....
And the shot were the fighters take off to fight the Death Star was redone - I don't remember if it was for the 1978 mono mix version or for the 1981 version.
