Hi, I have a Pentium III PC with NVIDIA GeForce 7300GT on an AGP 8x and am running NVIDIA driver 9755 on CentOS 5.0 x86. What is the most efficient playback method for the various players, XVideo or OpenGL? RealPlayer has a "Use XVideo" tick box under the "Hardware" tab preselected, while MPlayer uses xv - X11/Xv, gl - X11(OpenGL) and other Video drivers. What is the most efficient between the two, given the configuration?
