This is rather convenient. I have an Epox 8RDA+ as well. What video card are you using in that box? I'll install mplayer and see if I can replicate (I have an ATI 9800 Pro, but I can easily stuff a number of nvidia cards in there to check). If you're using an ATI or Nvidia card, are you using the proprietary or opensource drivers?
