I think the THX logo commonly included on THX mastered DVDs and laserdiscs (LDs) is about half as long as the introduction used in movie theaters some years ago (approximately 15 seconds on DVDs and LDs versus approximately 25 seconds for the introduction used in theaters). If I remember correctly, the long THX theatrical introduction shows the statement “The audience is listening.” Several years ago, I was shown a laserdisc that had the long THX introduction on it, but I cannot remember the name of the disc or who made it. I think it was a demo LD that may have been included with the purchase of a specific LD player, perhaps a Pioneer LD player. Can anyone confirm if the long THX theatrical introduction exists on any DVD or LD? If so, can you please tell me the name of the disc and where I might be able to find a copy? Thank you in advance for any replies.
