"try to change -dumpstream with -dumpaudio"


Sadly that just makes things worse.    If I do that I can't even play 
the resulting file in mplayer, let alone the official realplayers.

At the end of capturing the audio stream I get

"Unknown extra header dump: [80] [0] [10] [0] [17] [0] [80] [2] [10] [0] 
[1] [0] [0] [3] [8] [0] [0] [25] [0] [0] [0] [0] [0] [2] [0] [4]

"

Here is the output of mplayer -v on the file that was produced.
