The new DreamboxManagerSuite don't need an installed VLC on your computer.
In the suite itself are included all VLC libraries which needed, so its equal what the version of VLC do you have installed.
If you interested take a look in the installation-folder of the DreamboxManagerSuite in the subfolder DBMS VLC.
I installed the latest update and got the video streaming to my PC no problems (did not work before the update). The screen shot is however not working.
