This problem appears to be caused by the "output" option being set to automatic.
Results may vary, but I have found changing this setting from "Automatic" to "Windows GDI video Output" has worked for my computer.
After changing this setting and restarting VLC, videos resumed playing in the VLC skin I was using.
EDIT:
I have found certain video encoding formats appear to have issues with this output module, there are a few different options to pick from, see what works best for you from the list.
It also seems as though some people only have this problem when using the Windows context menu and selecting "Play with VLC Media Player"
Another workaround for some people is to select "Add to VLC Media Player's Playlist" instead.
