VLC on MacOS en tvOS 4k video playback

Hi All,

I have a very strange issue while playing 4K video's via VLC on my Macbook and Apple TV.

I really rely on VLC for playing those files since they contain audio in DTS-HD. If I use the DS-Video app from Synology the video plays without issue but without audio.

So via DS-Video the image looks as follows:

But if I use VLC to play those 4K files I get a strange behaviour (blur) on the right of the screen (sometimes it is on the bottom, depending on the video). Tested on MacOS and tvOS.

It looked to me as something with bad de-interlacing, so I changed the de-interlace setting from "Auto" to "On". This gave the result that I loose I piece of the image. (only tested on MacOS), for tvOS changing settings doesn't solve it.

The problem exist on my Apple TV and my Macbook. Using VLC on Windows 10 plays the 4K files correctly.
