By following the tips in a very helpful forum "Fedora Core 4 Tips and Tricks" http://home.gagme.com/greg/linux/fc4-tips.php#mplayer I was able to get mplayer going, and I was so amazed as to how things have proved so drastically in Fedora in the multimedia area. I am now able to watch CNN news on my Fedora box, as well as watch some movies. However, on this DVD movie I am playing, I am getting the following error message: . . . cannot find 'dts' in libavcodec . . . I am able to play the video images without any problem, but I am not getting any sound. I have installed the "all-" codecs, but apparently this "dts" codec is missing. Any help will further improve the already great media capability of Fedora Core 4. Thanks in advance.
