[MPlayer-users] mencoder: Trying to convert real format to xvid

[Scott Cegielski]

Thanks for pointing that out.  I read the README files that come with 
the cvs source, but they are not as clear as the website it about what 
to do.  Anyway, I was able to build the cvs version successfully.  
However, the conversions still fails.  Here is the output:
