Well, I've sampled though some scenes for now, and I have to say: "Impressive. Most impressive." I didn't know laserdisc could look this good!
A few things to note:
we discussed about the audio, sounds like a bad remix. This was the THX VHS, wasn't it? Apparently THX has become a synonym of poor standards. Sounds like they took a music and effects track and mixed it with the mono italian soundtrack. Badly, because the music and effects are almost never in sync with the rest.
As a matter of fact, I was listening with headphones to the briefing scene before the battle of Yavin, and I could hear the lower end of General Dodonna's english voice bleeding though! If you pay attention, you can hear Luke and Biggs too. I think the problem is easier to spot in this scene because there are no sound effects or music to drown out the voices. I have never heard anything quite like this.
Of course, this is not a jab at you, my dear Andrea, this is just what you had to work with.
About the subtitles, maybe I did something wrong, but the only one that seemed to work was the second one, the dubbing transcript.
