We've released the very fist tool to help DVDx developers and users.:
http://www.labdv.com/dvdx/screenshots-infotool.php

DVDx InfoTool provides DVD structure (VTS, PGC, menus etc.) and video/audio/subtitle format from a DVD-Video (protected or not).

The very first pre-release is DVDx InfoTool 0.9.1 and is a providing informations as ifo _dump.exe and title_info.exe from libdvdread.

The informations can be displayed in 2 views: complete dump or "text" which filters out less useful detailed.

We're already preparing the 1.0.0 release which will display a 3rd view ("standard") with data formatted for a usage in a DVD ripper like DVDx encoder.

DVDx InfoTool runs on Windows, Linux and Mac OS X (Intel binaries provided).

DVDx InfoTool is available (including all compiled binaries) from SourceForge as part of DVDx project:
http://sourceforge.net/project/showfiles.php?group_id=72208&package_id=256669

Free open source code from SVN: http://dvdx.svn.sourceforge.net/viewvc/dvdx/trunk/

I've uploaded file today on SourceForge, enjoy!
