Turns out it was something completely different: in the ~/.mplayer/config file for the normal user, I had the line "vo=gl2" (which directs MPlayer to use the GL2 video output method; this was needed by the previous video card driver.) Root's MPlayer config file did not have this directive. Apparently forcing it to use the GL2 method is incompatible with the acceleration.
Thanks to Richard Blumel, who emailed me some advice off-list that led to the solution. Best, Aaron On Tuesday 13 June 2006 09:54 am, Aaron Maxwell wrote: > Hi.
