Hi there starking!
Welcome to LinuxQuestions.org. You're getting a black screen because you don't have the right codecs. I'd recommend you using mplayer
. It's a great player for practically everything: Dvd, VCD, ogg, mp3, DiVx.. you name it.
You can also grab the latest codecs from their download page. I believe mplayer's codec would also work with Xine (never tried myself, but since they work with avifile, I'd guess it should also work with everything else).
If you choose to install mplayer, compile it from source, it's just better and easier then rpm's in this case. Read the README docs before download/installing anything. It's pretty easy to install. If you have any problems or do not understand any part of the doc, let us know.
