Category: Multimedia files
Programs that use the .wmv file type: Various media players
Explanation of .wmv file extensions:
The .wmv file extension, which competes with the RealVideo format, is a compressed video format original designed to stream applications over the Internet. The .wmv stands for Windows Media Video.
Typical problems associated with the .wmv file extension:
One of the most common problems with .wmv files is an annoyance. Most of these files contain Digital Rights Management Systems which make the files unplayable on players that do not support the standard Windows Media DRM systems even if you have paid for the rights. For example, the Microsoft Zune does not support this system.
Another common .wmv problem occurs when the Windows registry contains invalid instructions, missing file associations, or has had references to .wmv files removed by spyware or other processes.
Solutions/Recommendations:
First, make sure you are using a compatible media player when trying to open .wmv files. Compatible players include Windows Media Player, PowerDVD, Media Player Classic, MPlayer, RealPlayer, and VLC Media Player. While the Microsoft Zune player can handle .wmv files, it cannot handle those with standard Windows Media Digital Rights Management incorporated.
Run a registry cleaner to resolve many common .wmv errors including lost file associations and file corruption. Anti-virus and anti-spyware programs should scan any incoming .wmv file for viruses and spyware.
