NVIDIA 344.11 Driver Bug
The latest NVIDIA graphics driver has a bug that can cause playback to fail for files that contain 10-bit H.264 video. This type of video is not very common, it is mostly only used for Anime videos. There is a simple workaround to avoid the problem: Disable the P010 output format in the settings of LAV Video decoder (or ffdshow if you still use that).
