Hello all... I would like to ask that is KDE is need fast CPU? Because when I use Mplayer to play movies in Gnome environment, the Mplayer didn't displayed error. But when I change to KDE. The Mplayer displayed "cannot open /dev/dsp or device busy" and I clicked the "OK" the movie can play. Do I need to upgrade the hardware or fix the KDE ? Sorry for my english bad... Wong Kwok Hon
