Paul, mplayer -vo xv file.mpg plays very well, but pins the CPU. There are some complaints in the output about having too slow a CPU and something about the audio, but it plays quite well.
mplayer -vo xvmc file.mpg plays for about a third of a second and aborts. The error complains about a video filter and even recommends adding a video filter at the end of the -vf switch, but when I put -vf in mplayer says that it is not a valid option. I'm not sure what else to try. Thanks for all your help. On May 20, 1:18 am, Paul <pwoodw...@wwf.org.uk> wrote: > try using mplayer to test.
