I was reading old mails from the list to get some tips for my work and I've found this one.
I think most of us have only read the first part, since nobody answered the questions; nevertheless I think they deserve an answer which I'm not able to give. If someone is, I would really appreciate the reading.

>-CS with a RTSP server is almost ever used in multicast mode

>Sending request: SETUP rtsp://genius:9999/007/track1 RTSP/1.0
>User-Agent: VLC Media Player (LIVE.COM Streaming Media v2004.01.19)
>Received SETUP response: RTSP/1.0 200 OK
>-CS used without a RTSP server: can we use both multicast or
>unicast in the
>same way they are used with a RTSP server ?
>-VOD is almost ever used with unicast but
> is it POSSIBLE to use it in multicast mode whatever the sense
>it could have?
>I mean to connect to RTSP port and during the negociation, instead of
>choosing unicast destination, choosing multicast one for RTP.
>If yes, how ?
