Inferno seems to be a tough call. If I compare shot 01 at caps-a-holic.com ( http://www.caps-a-holic.com/hd_vergleiche/multi_comparison.php?disc1=1242&disc2=1243&cap1=11871&cap2=11883&art=full&image=0&hd_multiID=84&action=1&lossless=#vergleich ) I would prefer the AT Disc compared to the US Disc. But Shot 03 would let me chose the US disc..
I don't know how the FR disc is, I just had it in my hand a few days, and it kept sealed... :)
Maybe it should not be a BD 50 trilogy disc, but three discs, with each one movie, containing a selection of two of the remarkable transfers. With the best posible audio for both versions. ^^
i.e. Inferno could be a collection of the US and the AT Version...
Allready owning the AT Discs for all three Movies a disc with foreign harder to get transfers would be more interesteing then a disc with the three AT Versions losing the german audio track...
