Forcing 16:9 crop on Youtube videos in youtube.lua?

[dasfgh]

I'd like to play Youtube videos in VLC Player so I can use it's 16:9 crop to fill the entire screen when watching 4:3 videos on a 16:9 fullscreen. I turned on that option in Tools > Preferences > Show Settings : All > Video Cropping: I entered 16:9 here.

Now, the VLC player does play most of the Youtube videos in 16:9, however some videos still appear in 4:3. I don't know why. When this happens, I have to turn on the 16:9 crop manually (right click > video > crop>). I was wondering how can I force it to always display Youtube in 16:9?

In the beginning, the VLC Player couldn't play any Youtube videos, but I downloaded a youtube.lua code and solved the problem. Now the player plays all the youtube videos that I want. The problem is just how to force ALL the videos to be 16:9 without having to turn on this option manually from time to time. I was wondering, is there any setting that I can change in youtube.lua to force this?

Thank you.
