Re: GT230M and 195.36.24: Stuttering when playing video with HDMI
As far as i know using only the -vo vdpau switch mplayer will use software codecs thus leading to high CPU usage in case of HD movies.
mplayer -vo vdpau -vc ffodivxvdpau,ffh264vdpau,ffmpeg12vdpau,ffwmv3vdpau ,ffvc1vdpau
in order to use hardware vdpau decoding - you can use only one argument to -vc, but you must know the exact encoding of the file - this way all (presumably) movies will play through hardware vdpau decoding.
You can use pulseaudio for easy output switching, with -ao pulse (mplayer works well with it). Then you configure the pulse server as you like.
