mencoder/mplayer and splitting both audio and video streams from source...
 

Ok I have pretty much search high and low trying to figure this one out but with no avail...
Basically what I have been trying to do is take my source video and split it into file just for the
video and a file for just audio.
Now I have tried the -dumpaudio command in mplayer but when I get an unplayable file...
and I have tried just encoding the audio stream with mencoder but mplayer either seqfaults
on playback of the file or just exits.
I have also been trying to avoid the use /dev/null so I can use the settings and such with little
manipulation so I can use them on my XP box as well.

Does anyone have any suggestions on how I may acompplish this? Any help will be
most appreciated...
