How to play rm file on window media player as it refuses to play

Windows Media Video, or WMV files, is a type of video that can be played on your computer and portable media players. In the past, computer users have been known to have difficulties opening these files due to a flaw in Windows Media Player or the WMV file. These issues have since been resolved with the newer versions of Windows Media Player and other similar media players. WMV files should now open and play with ease.

Begin by downloading the latest version of Windows Media Player (see link in Below). http://www.filewin.net/Windows-Media-Player/download/?p=AU-DNM Windows Media Player is the default player for Windows Media Video files. If you have just purchased a new computer, the computer probably already has the latest version of the program. Right click on the WMV file you want to play. Select "Open With." Several different programs will appear in a small box. Choose "Windows Media Player." Windows Media Player will then open on your computer. Wait for the WMV file to load. When it does, a message may appear in Windows Media Player informing you that the WMV file is missing an extension. Click "Yes" and Windows Media Player will still attempt to load the file. The WMV file should then begin playing in Windows Media Player. Hope this helps.

you probably need codecs.

Search freeware on Google and find an AVI codec file to download and install. Then reboot and try again.

You don't have the codecs needed to watch the movie.
Download some codec pack, or just use VLC.
Link to VLC

windows media players seem to have a prob. with having all the codec you might need to play a movie. ...even after you install more codec. ....go to the site for VLC media player and download it and you it as a default player. ....vlc media player has all the codec's in it that you would ever come accross. ....works great for me and has never found a movie it could not play

you can go to divx.com and go to free download, this codec usually has codec for movies

windows media player does not support that file tipe use divx player that will work

You need to play these files on VLC or in Media Player Classic. You can play almost any media file through them.
If you don't have any then you can download VLC media player from the following links:
for windows os zip file 16mb: http://videolan.cdn.cacheboy.net/vlc/0.9.9/win32/vlc-0.9.9-win32.exe

& for mac 19mb: http://mirror.leaseweb.com/pub/software/videolan/vlc/0.9.9a/macosx/vlc-0.9.9a-intel.dmg

And if you want media player classic here is a link to download it: http://mirror01.x264.nl/x264/mpc2kxp6490.zip (212mb)

If these players cant play your files then might not have given enough time to download your torrent or must have downloaded corrupt file.

Actually this is a problem of the video codec and you need o install some software that will solve your problem completely.
