If the video fails to load, it is because you are most likely missing the correct DirectX video codec. The best advice is to do one of the following:
·Install the software that came with your video camera. It may also have come with a DirectX video decoder that would allow other programs such as Windows Movie Maker or Windows Media Player to play the files. (This assumes that the file was created with a video camera that you own.) Make sure to restart your computer after installing.
·Download a video file converter to convert it to AVI or WMV. This is better than loading the original video format, as it will be faster.
·Install a DirectX/DirectShow video codec. for the video format you are attempting to load. Beware of many faulty/buggy/error prone decoders out there on the Internet, partner.
·Install the latest version of Windows Media Player.
