DAT is a VCD file extension used in the Microsoft Windows Operating System to mean "video data" normally. It can be encoded with MPEG 1.0, 1.1, 2.0 standard.

WMV contains video and audio streams respectively using Windows Media Video codec and Windows Media Audio codec. 

To convert DAT to wmv file, if the dat file is encoded with mpeg1.0 format, you do not need to install any additional dat decoder. If the dat file is encoded with mpeg1.1 or 2.0 format, please install DVD players which include the appropriate dat codec. Please ensure the *.dat file is video file and Windows Media Player can play it because many other files also use this kind of extension. VISTA has bundled DAT 1.1/2.0 decoder.
