Video playback black - UV+16, Vista Pro 32bit

[WorstCases]

Hello folks,

I have the UV+16 and everything is fine, but I can't get Videos of any kind to work on the screen.
No matter if I try to start playing a Video or move a running video from the main screen. As soon as it gets on the DisplyLink screen, the playback are is black. Window or full screen - no difference.

The problem persists with different players (VLC, KMP, Video Edit Software, Windows Media Player).

I tried to google the problem, but did not find anything. I wonder if I really am the only one with this issue...

I did attach the log file from the DL Support Tool.

Anybody any input?

Thank you.
