GoLight, are you using either VLC version 2.1.0 or 2.1.1? If so, I would uninstall VLC, delete any remaining VLC appdata, then do a clean install of VLC version 2.0.8. I have heard a number of VLC users (not OpenLP users) reporting video glitches with the 2.1.x branch of VLC.

As it happens, I found myself installing VLC and OpenLP on a new Windows 8.1 laptop this morning. I chose to install VLC 2.0.8 to use with OpenLP 2.0.3 and it worked well. The final test of course will be this Sunday!
