It's meant to end quickly for encrypted channels (cause mplayer can't 
play them).  Did you try it specifically on a non-encrypted channel and 
it still ended too quickly?  It's not too important because using grep 
will do the job, but like you said, it won't get rid of the music 
channels.  In theory using time will be able to get rid of the music 
channels too.
