I've just got confirmation from a Laserdisc collector in Italy and he says that THX on Laserdisc only exists in English NTSC (from US) and PAL (from UK). There are no Italian, German or French version of the film on Laserdisc.

You forget the Japan Laserdisc in NTSC, and the UK one supposedly is not uncut, but essentially you are correct. I am still waiting on hearing whether or not the japan version has cuts or censors, since long ago i read that it censored the sex scene.

The Japan version was said to have a better print and sound in English with burnt in Japanese subs. Since the guy selling it for over a hundred dollars claimed these things i was skeptical since you can get the us laserdisc usually for over 25 bucks on Ebay or on the laserdisc database.
