i am using fedora 9 and have installed
1. VLC
2. Gnome Mplayer
3. XIne
4. Real player 11
5. Movie player

When i try to play any divX files in them..
1. VLC just crashes
2. there is sound in Gnome M player but dont show the video
3. Xine just shows a white screen neither audio nor video
4. Real player shows an error that it is unable to play the content
5. there is sound in movie player but no video.

First you must install some video and audio codecs from Livna repository. For detailed information look at this guide:

Fedora 9 Installation Guide

Sounds like a codec problem to me. The players itself does not fully support a load of video codecs, and require additional to help play them

[Edit] oops, sorry, didn't know this was for linux

Actually, your post is equally accurate for Linux.

If the thread started follows MysticGr's advice, I think that will allow him to play all his media.
