These are no playlists, they are direct URL addresses to live streams (radio
stations). I don't get any error message, mplayer works properly: the resulted
file (live.rm) is of a certain length and size (1.6MB), but there is no sound.
As it is LIVE, hence infinite stream, I need to interrupt the capture.
I do have the required REAL codecs as the capture works for any other NON-LIVE
RTSP/MMS streams(.rm).

Thanks.
