WMV video file format :
WMV stands for Windows Media Video -- developed and controlled by Microsoft. WMV is a generic name of Microsoft's video encoding solutions and doesn't necessarily define the technology what it uses -- since version 7 (WMV7) Microsoft has used its own flavour of MPEG-4 video encoding technology. DivX video format is originally based on hacked WMV codec.
