I love the VLC player as it plays videos that I would otherwise not be able to play. But I have this one problem with it. In certain video files, there's this yellowish grid that flickers in over the center of the image from the top of the image to the bottom. I distorts the colors underneath the grid too. Most of the language in the settings and such are a bit over my head. This has happened with a few files I've d/l'ed from Youtube as well. Does anyone know how to correct this? Thanks.
