Display resolution vs resolution?

I make H.264 mp4s in adobe premiere cs6. When I open them in VLC and go to Tools > Codec Information it shows Resolution: 720x418 Display resolution: 720x404
It does this despite any settings in premiere. I've tried making a custom sequence with square pixels. I've tried DV - NTSC widescreen. My render settings are also always square pixels. Nothing changes it. My HD footage in vlc shows resolution: 1920x1090 and display resolution 1920x1080
This display resolution setting only seems to have appeared as of vlc 2.2
Any ideas?

That's normal. You should care about the display one, only.

I need to know the technical reason why it is showing a different resolution. Please explain.

Buffer size vs display size.

Please consider changing the wording from Resolution to Buffer size then so it doesn't confuse users.

Yes, this would be interesting for me, too.
Also no answer in this thread:
https://www.reddit.com/r/VideoEditing/c ... c_info_as/
In my case: HD video with square pixels = 1920 x 1080 px – but VLC displays it in a height of 1090 px:
Making screenshots
within VLC: same "wrong" size

Therefor I can't advice this program for this purpose.
I opened the video in Photoshop, Premiere and so on: each time these programs show me the "correct" height of 1080 px – whats going on in VLC?
Any explanations?
Thanks a lot!

Come on. The answer is actually in that thread:
VLC admins told me that it's normal and the "resolution" is actually "buffer size" I told them they should rename it buffer size then.
(VLC 3.0 uses the improved terminology.)

Come on. The answer for the correct English equivalent for "Auflösung" is already said.
But we – @cinmed, too – want to know what this buffer size means. And accordingly how it is possible to create snapshots NOT in the dimensions of this strange "buffer size", but of the real video size.
Thanks again, Rémi Denis-Courmont!

... ah, the "wrong" Buffer size is only shown in newer versions of VLC, older ones do not have this bug.

Sorry, but I still don't get it. The meaning of "Buffer Size" as opposed to "Display Resolution" is still not clear to me.
So far I understand that the "real" resolution of the video is the "Display Resolution". So, when having 1920:1080 with square pixels, that's a DAR of 16:9, right?
So, where does the "Buffer Size" of 1920:1090 come from then?
