Traditionally status messages tend to be sent to stderr
rather than stdout (this means that they don't break Unix 
pipelines). But that means that to read them you will need 
to use popen2 (Or the new subprocess module) to access stderr.

I don't know for sure that mplayer is dping that but I'd say 
its a strong possibility.
