Hi everyone, I have recently installed fedora 9 sulphur in my machine (hp dx2300). The system works beautifully except for one small glitch. When I try to play videos in fullscreen using any player e.g mplayer, gnome, totem, the video drags as if playing in slow motion. At normal size (small) they play OK. When I disable the desktop effects, the videos play normally even in fullscreen. A buddy of mine suggested something about my system using the CPU not the GPU for processing the videos. I dont know what that means. I doubt it could be my video card since videos play fine in Windows and Ubuntu. Any help will be greatly appreciated.
