[MEncoder-users] demuxing a radio stream

[David de Beer]

On my satellite PVR I record the usual films of course, but radio broadcasts 
as well.
The PVR records the broadcasts as a .rec file, which can be listened to with 
mplayer.
But, they have a gigantic overhead on a non-existing videostream, plus 
sometimes I would like to burn the contencts on CD, edit the files to keep 
the music alone etc etc..

Now demuxing poses a problem. No matter what combination of commands I tried 
so far the result is:'Video stream is mandatory!'

in mplayer I get the settings as below on playing, please help me out if you 
know a way to demux the file by use of mencoder.
The combination might exist, I hope.

greetings,
David
