recorded a stream, but cant play it

[pc10pc]

hi
i recorded a long radio show using the raw output, which has given me a file of just under 400MB.
normally i just append .mp3 to the filename and i can play the recording in any media player, but not this time. VLC looks like the file is opening but after a few seconds of silence just stops.
im using a shell script in ubuntu to do this

Code: Select all

vlc --run-time=25200 http://www.live365.com/play/319909? --sout "#duplicate{dst=std{access=file,mux=raw,dst=/home/paul/mfn}" vlc://quit ;

i tested it beforehand, recording a few minutes then renaming as .mp3 and it worked fine?
can anyone help rescue my recording?
