Thanks!
The OUT 2.0 will be slightly better, both audio and video.
On the back cover of the french laserdisc, is not stated that the french soundtrack is Dolby Surround, but only stereo. But, as all the other PAL THX laserdiscs (and italian VHS, too) are Dolby Surround, maybe is not stated on the cover, but IT IS Dolby Surround encoded - sometimes is not stated to not pay royaltes to Dolby...
Well, in the OUT 2.0 the only audio conversions will be from 25fps PCM 1441kbps to 23.976 AC3 384kbps.
I'll wait for your subtitles.
