I hate to call back to some older discussions, but I remember it got a bit confusing there.

What are the best versions of the Transporter films (as far as film content)?

From what I can tell:

Transporter 1 - Japan R2 for being NTSC, DTS and having the 2 extended fight scenes. (Although a fan edit with all extended fight scenes would be better.)

Transporter 2 - France R2 for being uncut and with the improved CGI.

Transporter 3 - Any version.

Sound about right?

Transporter 1: seems to be the japanese DVD

Germany has the extended cut of Transporter 2 on DVD OFDB Info. Called "Director's Cut". Running Time in PAL: 90:24 Min while French DVD has a PAL running time of 84:30 Min. http://www.movie-censorship.com/report.php?ID=1875776 Here is listed whats more in german "Director's Cut" Version.

Transporter 3: right.
