You need to download a viewer for avi files

I suggest you download and install VLC Media player instead of using windows media player. VLC is capable of playing all sort of media format.
Download VLC Media Player on the link provided.

Hi,
To play the avi files. you can try to options.

1. You can download a different media player which is VLC media player. It plays almost all kinds of video format.

2. Download K-lite codec and run it and you should be able to play .avi files in media player.

Hope it helps :-)

i would suggest either getting windows xp or 7, vista has alot of bugs

Use VLC player to play any kind of video files

That sounds like you don't have the proper codec to play AVI files. Even if you haven't had problems with AVI's before these files may be DIVX avi's instead of the usual Xvid. Download the full codec pack here: http://www.codecguide.com/download_kl.htm and install it. Restart your computer and try again and you shouldn't have any problems.
Please rate, thanks!

Try downloading this and install it...

1. WINDOWS XP;

Hi,
Windows Vista Media Center won’t play Xvid and Avi files, even if Windows Media Player will play these files. If you want to add support for third party codecs including Xvid and Avi files in Vista Media Center then you need to install the media control plugin for Windows Vista Media Center.
To install the Codec please click on the below link or copy the URL and paste it in your web browser..
http://damienbt.free.fr/index.php#download
This plugin allows Windows Vista Media Center to utilize te FFDShow decoder, which needs to be installed seperately ((FFDShow rev 1108 recommended: download the last version from http://sourceforge.net/projects/ffdshow-tryout)) FFDShow adds support to Vista for MPEG-4 video formats like DivX, Xvid, H.264 and also alllows MP3, AAC, Dolby AC3, and OGG Vorbis audio files to be played back.
have any other queries, please let me know..
Thank you.....
