While loonig up one of the errors in the mplayer trace I've just posted, I found this thread: http://www.nvnews.net/vbulletin/show....php?p=1936545
where a user recomends adding -demuxer lavf to mplayer's command line. This decreases cpu usage from 100% to under 30%; however, after some seconds, video and audio begin to stutter and I get this on the terminal:
Too many video packets in the buffer: (249 in 33627394 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
