The parameter to change I was refering to was the 'Subtitle track' auto load parameter, under VLC preferences.
About VLC not working anymore, maybe you changed the 'video track' load parameter? Tried reinstalling?
PS: got an email?
there're some rtsp online radios that I've never got to play.VLC can both play and stream RTSP.
to stream RTSP, you must use the VLM component : http://videolan.org/doc/streaming-howto/en/ch05.html
