But still, the video has been touched for some reason, even though Ridley Scott is usually a good preservationist.
What do you mean by touched? Are you talking about the "Director's Cut" or the new timing on the blu-ray that caused some controversy? Either way, when it comes to Ridley's films, there's always a choice and they are treated like films and not like some computer software.
EDIT: Started a thread about the Alien audio: http://originaltrilogy.com/forum/topic.cfm/Dolby-Digital-41-Surround-Alien-Anthology/post/568250/#TopicPost568250 so that we don't derail this thread any further.
