Hi. For a long while I tried unsuccessfully to have my Linux machines able to play video formats, like WMV, MPG, AVI, etc. Finally I found a way to do it very easy in Fedora Core 6. Here's a guideline that I hope will help other people who may need it. -- STEP 1 - set the repositories. As explained in - http://www.fedorafaq.org/#installsoftware just type in the following command at the Terminal STEP 2 - install Mplayer plugin ( http://www.fedorafaq.org/#browsermovies ) Type in the following command STEP 3 - install the complementary Mplayer GUI and supporting libraries Select 'Add/Remove Software' and search for 'mplayer'. Select as shown and then click 'Apply'. STEP 4 - install the codecs for Mplayer Follow the guideline in http://stanton-finley.net/fedora_core_5_installation_notes.html#Codecs Only be aware to change the following items accordingly: - site - http://www.mplayerhq.hu/MPlayer/releases/codecs/ - file - all-20061022.tar.bz2 -- That should be it. Enjoy.
