When I open my video folder, the thumbnails aren't showing. Instead, the default VLC icon was being displayed. Other files and image thumbnails are being displayed properly, only the videos have problems.
The "always show icons, never thumbnails" option is unchecked.
What could be the problem?
I have also installed the K-lite codec pack, I tried clearing the thumbnail cache, but it's not working.
My problem is similar to this, but with videos: Windows 7: Image thumbnails fail to appear
