Play two files synchronously and control from one instance

[owl_123906]

Hello everyone,
Using the latest version if you want to open two files and play synchronously, open multiple files under "Media" doesn't work. I found this command to do that:

set videoPath1="C:\Users\abc\Desktop\video1.avi"
set videoPath2="C:\Users\abc\Desktop\video2.avi"
start /D "C:\Program Files\VideoLAN\VLC" /min vlc.exe %videoPath1%
start /D "C:\Program Files\VideoLAN\VLC" /min vlc.exe %videoPath2%

It works perfect and both files open and play synchronously. But if I click pause or change the speed, only one instance reacts. Is there a simple way to control both instance through one? So if I click space, both should pause and next time I click space, both should start at the same time etc. (Just like it worked in 2.2.8 Version)
Thanks for your help.
