So my idea was not so wrong... just maybe changing title of the thread to "The Laserdisc (and other sources) Audio Preservation Thread" is not so wrong...
I suggest this because it will help to grab attention even from outside, as google (and the other search engines, also if used by the minority of internet users) shows the thread title in its search results, and if, for example, a non-OT user is interested in a laserdisc audio preservation, may find interesting the result from its title, click the link, and became a new OT member...
