Video Drivers - Intel NUC

[shlee-c]

Hello,

I am running Kubuntu 16.04 on an Intel NUC core i3-61. Overall it works fine, however there seems to be a problem with hardware acceleration (not sure, I am a beginner ) .

Whenever I play a video in VLC player (or Dragon player), The video appears very small in the middle of the program window. It does not change size when the program window is scaled, and it appears always on top of all other windows on the desktop... but without the program window frame around it. When shifting the window to another position the video stays where it was until the mouse button is released.

I was told hardware acceleration is an issue or there might be a driver conflict and I started with lshw -c video:

I wonder why mpeg4 is not listed and why driver names in both outputs do not match.
Maybe the right driver is missing?

Hope someone knows what do to next.
Thanks in advance!
